With the changes in the international situation, the contradictions between the East and the West have gradually heated up.
This is manifested in the recent Russia-Ukraine conflict, although Western countries led by the United States have provided a large amount of military assistance to the Ukrainian army, but the situation of this war has gradually tilted in favor of Russia.
Recently, the Commander-in-Chief of the Armed Forces of Ukraine Syrsky posted a message on social **, saying that due to the current battlefield situation, all participating troops stationed in Avdiivka have completed the withdrawal of troops to protect their lives, and the Ukrainian army has retreated from the city to a more secure area conducive to combat.
The importance of Avdiivka, a military fortress of the Ukrainian army in the Donbas region, cannot be overstated. Although in the early days of the Russian-Ukrainian conflict, the Russian army quickly occupied the Donbas region, Avdiivka has always been an important line of defense for the Ukrainian army's resistance.
However, now it seems that this important place has been broken by the Russian army, and the Ukrainian army has been forced to retreat. Despite the fact that the commander-in-chief of the Ukrainian army called it "a retreat to a more favorable line of defense", it is undeniable that the line of defense has been lost.
So, how did the Russian army break through the Avdiivka line? In fact, in order to pull out this "nail" in eastern Ukraine, the Russian army has been trying to attack, but because the West continues to provide the Ukrainian army with advanced equipment, such as "Hippocampus" rocket artillery and "Leopard 2" main battle tanks, the Russian army's offensive has become difficult.
Therefore, the Russian side adopted the tactics that we are familiar with - "tunnel warfare", and finally succeeded in breaking through the Avdiivka line.
Avdiivka, a military fortress in Ukraine, has been surrounded by tens of thousands of Russian troops since the second half of last year. After the Russian army used air strikes to break through the defense lines of the northern and southern flanks of the Ukrainian army, it began its own tunnel tactics.
In November last year, the Russian army secretly dug tunnels and successfully blew up the positions of the Ukrainian army, which caught the Ukrainian army by surprise. Today, the Russian army is able to break through Avdiivka, and tunnels play a key role.
There is a kilometer-long disused sewer line under Avdiivka, which has existed since Soviet times. Through secret excavations, the Russian army arrived here, successfully broke through the Ukrainian defense line, took the core area in the city, and forced the Ukrainian army to withdraw.
Staying in the city, the Ukrainian army will undoubtedly become the "dumpling" of the Russian army.
Although the Russian army is advancing into the hinterland of Ukraine, it is not easy for the Ukrainian army to retreat, because the Russian army is constantly pursuing and attacking. The 110th Company of the 3rd Brigade of the Ukrainian Army has been eliminated, the heavy ** has been abandoned on the side of the road, and the captured Ukrainian army said that the army's communications have been cut off.
This suggests that even if the withdrawal is successful, the Ukrainian army may suffer significant losses. For Ukraine, the fall of Avdiivka was a heavy blow. At the military level, Avdeyevka is just a few hours away from Kyiv, mostly plain.
With the loss of military fortresses, it will be more difficult for the Ukrainian defense line to withstand the air strikes of the Russian army. And if the Russian army captures this place, they will join up with the army in the Donbass region, fully approach the Ukrainian hinterland, and push the front deeper.
This is undoubtedly a huge pressure for Zelensky.
Although Zelensky did not receive any positive answers during his phone call with Biden, he had good news: Biden did not abandon him.
After the destruction of the military stronghold of Avdiivka, the U.S. Senate passed a foreign military aid bill that included military aid to Ukraine and Israel, with a total value of $95 billion.
However, Biden has been a strong critic of the delayed actions of the congressmen, calling their actions "ridiculous and immoral" and saying that he will fully support the extension of US military assistance to Ukraine.
While Zelensky's promise and the U.S. aid bill have given Zelensky some comfort, it's hard to determine exactly how much aid he will receive. After all, anyone can see the current predicament of the Ukrainian army, the two sides are getting closer and closer to negotiations, and continuing military aid to Ukraine may only be a waste of resources.
In addition, it is an important moment for the two parties to seize power in the United States, and the biggest achievement of the Biden administration is to use Ukraine to consume Russia, but the Republican Party has not been very active in this matter, and Trump is menacing in the election situation.
Once the throne changes hands, these promises will undoubtedly face uncertainties.
