Since the war between Russia and Ukraine started on February 24, 2022, many people have firmly believed that Russia can take Ukraine in a short period of time and force it to surrender, and will not join NATO forever.
Who made Russia's military strength firmly ranked second in the world, and its opponent Ukraine only ranked 22nd. The military strength between Russia and Ukraine is 20 different from Ukraine. With such a big gap, anyone would say: Russia can win Ukraine in a short period of time and will never fail.

However, the facts interpret the sentence, "Ideals are full, and reality is the backbone."
The Russian army's special operation against Ukraine began in February and until today, and there is no sign of ending. During the entire process, Russia proposed two or three negotiations, hoping to resolve the protracted war.
However, Ukraine did not refuse immediately, but the bargaining chips proposed made Russia very angry. If Russia accepted the conditions proposed by Ukraine, not only will the war be completely defeated, but Russia's international status will also plummet. Russia will definitely not accept Ukraine's strict requirements, but instead intensified air strikes on energy, power plants, roads and other infrastructure in Ukraine.

There is a saying that goes very well, "What you can't get on the battlefield is even more accessible on the negotiation table." Seeing that the Ukrainian army has taken the initiative on the battlefield, it is impossible not to propose some favorable conditions.
When the battle between Russia and Ukraine ends depends on the meaning of the United States behind Ukraine, it is no longer transferred by Russia's will.
The reason why the Russian-Ukraine war has not ended for more than 9 months is beyond the expectations of many people, and the performance of the Russian army has also surprised many people and countries. The main reason is determined by multiple aspects, not only related to NATO's support, but also to Russia's own military construction.

The impact of NATO aid
Everyone knows that Ukraine's own military and strength are not very good, such as the most used individual air defense and air defense missiles, anti-tank missiles, , and high-precision rocket launcher , so there are very few. Without NATO's support, Ukraine would not be able to get the torrent of the Russian Army.
cannot be said that Ukraine does not have the ability to produce its own individual air defense and anti-tank missiles; it can only be considered that the number is very limited and cannot stop the Russian army's attack at all. Even the war had ended long ago and Ukraine surrendered.

However, after the Ukrainian army withstood the Russian attack, NATO's military aid also arrived very timely. From early stingers, javelins, NLEW, Starlight and other individual equipment; to today's Himas rocket launcher , M-177 howitzer, Divine Sword guided shells, T-72 main battle tank , various drone , armored vehicle , unmanned attack ship, night vision , etc., plus NATO information support.
After NATO-assisted equipment was fully received, the Ukrainian army withstood the Russian army's attack, and then they could launch a series of attacks on the Russian army's armored forces, fighter jets, and armed helicopters .

thus slowly reversed the situation and now he has taken the initiative on the battlefield. Despite NATO's support, the Ukrainian army still suffered heavy losses in the face of Russia's naval and air superiority.
In other words, without NATO's support, Ukraine would not have been able to withstand such a long time. Even after the war of attrition was fought, Ukraine was consumed in 9 months.

The impact of the Russian army's own construction
Only from the equipment of Russia's navy, army and air force, it is definitely the second strongest military power in the world. The most critical issue is that Russia's weapons and equipment development direction is incomplete, and it can also be said that it takes a detour and focuses on the development of some heavy equipment.
such as T-14 main battle tank , Su-57 fighter , zircon and dagger hypersonic missile, nuclear submarine . It is understandable to attach importance to the development of the above weapons. After all, Russia's ultimate opponent is the United States, and there is no confidence to not have enough weapons to deter the US military. This is understandable.

However, for example, precision guided bomb , which is easier to consume in conventional wars, all-in-one drones, reconnaissance drones, air-to-ground missiles, , etc., there are very few, and their own battlefield situational awareness capabilities are not strong, of course this is not a problem for the Russian army.
is mainly because Russia's electronic information technology is poor, and its military expenditure is extremely limited. The Russian army also wants these high-end equipment. The key is that the entire country's industrial strength cannot be provided, and in the end they will have to end up in vain and fight whatever weapons they have. The weakness of

is that many expensive cruise missiles and ballistic missiles equipped by the Russian army began to throw them into Ukraine, and the fewer the more you go back.
is afraid of the Ukrainian army's individual air defense missiles, and the Russian Aerospace Army's fighter jets dare not attack ultra-low altitude air-to-ground missiles. There are too few air-to-ground missiles in the flying high altitude, and the reduction in the attack density of missiles.
Russian Army , which loses the above cover, in addition to having an absolute advantage in the main battle tank. The other precision guided weapons, , are not as advantageous as the Ukrainian army, so it is naturally more difficult to fight this battle. Of course, this is just a disadvantage on , a conventional weapon of Russian .

It is said that it is the people who decide the outcome of the war, but the size of the Russian army is not very large. After all, the army has a land area of more than 17 million square kilometers, with less than 300,000 people. Once it faces a multi-directional attack, the army will have insufficient troops at all.
Russia does not have the absolute naval and air force advantages as the United States. In many cases, the army is essential, and many tasks must be completed by the army. The army that has been trained for a long time is not enough, so it can only be temporarily recruited. Soldiers who go to the battlefield without training in modern wars are cannon fodder.

It can be seen that Russia's equipment development is unbalanced, the army is insufficient, and after too many casualties on the battlefield in Ukraine, it is difficult to launch a large-scale battle again, and it is finally here.
Overall, the reasons why many people’s predictions for the Russian-Ukrainian war failed are the above two points, NATO’s support and the imbalance in the development of the Russian military. However, Russia is unwilling to continue fighting to this extent today.
Ukraine said it was unwilling to negotiate, but there were not many serious Ukrainian soldiers. Many of the people active in the Russian-Ukrainian war were mercenaries or mercenaries disguised by NATO troops.

Finally, it depends on which Russia or NATO cannot support it first, or whether the United States' goal has been achieved. From the perspective of the interests of the United States, it will not disintegrate Russia, nor will the war last for too long. After all, there are many problems in the United States, and the goal of fighting to this day is about to be achieved.
