On December 27, Russia once again issued an ultimatum to Ukraine, and the news was reprinted with reference to the news. In the comment area, almost all netizens said that Lavrov was talking empty words: because the content of his ultimatum did look like empty words.
However, I think it is unreasonable to regard the words of a foreign minister as empty words. Because of this empty ultimatum, the reason is: Russia's Engels Strategic Air Base was bombed again on the 26th, and Serbia, , North Korea, and even Iran have all made changes in recent days... The Italian Defense Minister issued a warning: Russia may use nuclear weapons.
1. Empty words and an ultimatum.
At noon on December 28, some netizens forwarded Reuters news: Russia issued an ultimatum to Ukraine, requiring Ukraine to accept Russia’s negotiation conditions, otherwise it would be settled by the Russian military.

Reuters reported
In the evening, I saw the reference message forwarded by Tass News Agency . It turned out to be the speech of Russian Foreign Minister Lavrov in an interview on December 27. The original text is as follows:
"The enemy is very aware of our proposal on the demilitarization and denazification of the territory controlled by the (Kiev ) regime to eliminate threats to Russia's security from there."
"There is one more thing that can be done - accept these suggestions in a friendly way. Otherwise, the Russian army will deal with this problem."
"As for the possible continuation of the conflict, the ball is on the side of the (Kiev) regime and the Washington standing behind it. They can end this meaningless resistance at any time!"
This ultimatum is like empty words: Leave it to the Russian army to solve it. What have the Russian army been doing in Ukraine in the past 10 months! Many netizens commented like this.

Russia's burning cargo center
However, since Lavrov said this, there is a reason for him to be extremely angry; and the performances of all parties also vaguely cooperated with this ultimatum.
2. Direct causes and surrounding changes .
1. Direct cause: On December 26, Russia’s Engels Strategic Air Base was attacked again. According to Ukrainian media, its ground control center was destroyed.
This air force base is the main base of Russia’s triad strike force: the Aerospace Force. We do not know whether it stores nuclear ammunition. Whether there is or not, this has stepped on Russia's bottom line: Ukraine has begun to focus on hunting Russian strategic bases and strategic weapon launch platforms.
Russia will transfer its fleet to the Far East . So how can Russia prevent Ukraine from further actions: Let the conflict stop!
html On the 126th, "Donetskformer Defense Minister" Strelkov and a group of Russian military experts believed that the action against Ukraine must be escalated decisively!

What is decisive upgrade? There are means and scale. The scale has already been adopted. Russia has already adopted local mobilization orders. What about the means?
2. Peripheral changes.
Recently, Iran, North Korea, Iran, and Serbia, which have close relations with Russia, have either actively or passively shown extremely abnormal conditions:
One. North Korea: sent drones to fly across the dividing line and flew over Seoul .
South Korean Air Force fighter jets intercepted, causing a light attack aircraft to crash.North Korea possesses a powerful weapon. On the 28th, its drone flew over Seoul. What was it doing?
Second. Iran: In a message posted on the website by the spokesperson of the Iranian Ministry of Foreign Affairs, Zelensky said: "It is best for Zelensky to know that Iran's strategic patience with these baseless accusations is not endless!"
24 On the 124th, Ukrainian presidential adviser Podolyak called on the international community to destroy Iran's military-industrial enterprises : Bomb Iran with military means!

Serbia has deployed heavy artillery
Third. Serbia: The situation in Kosovo has been extremely tense: On the 26th, Vucic has ordered the country's armed forces and police to enter the highest state of combat readiness, expanded the number of the country's special forces from 1,500 to 5,000, and deployed heavy artillery on the edge of Kosovo. At the same time, NATO five countries issued a warning to Serbia: asking the Serbs to dismantle the northern roadblocks.
The situation in Kosovo is on the verge of breaking out.
All the above points are related to Russia! If Russia retreats again...Uzbekistan's latest price for peace talks is: try the Russian leader first, and then Russia can enter negotiations.
3. Warning from the Italian Defense Minister.
In such an environment, on December 28, Italian Defense Minister Guido Crozetto believed that Russia might use tactical nuclear weapons against Ukraine.
Guido Crozetto: "For us, the use of tactical nuclear weapons is unthinkable, but not for Moscow . This is within Russia's plan. If they face failure, they will definitely use tactical nuclear weapons."
In any case, Russia has not only been forced into a corner, but into a wall.
I hope that Lavrov’s ultimatum is really empty words, and that the Italian Defense Minister’s claim that Russia only uses tactical nuclear weapons.

Guido Crozetto
I hope there will be peace in the world.
