Putin was really angry this time, and he could even call it anger, so he didn't even attend the meeting.

(Ukraine successfully attacked several Russian airports)
According to reports from China Radio International and Global Network, the Russian Ministry of Defense reported that on June 1 local time, the Ukrainian army used a large number of drones to launch large-scale attacks on multiple military airports in Russia, causing multiple aircraft/pieces of aviation equipment to explode and catch fire.
The Ukrainian side's notification of the attack is like this. The Ukrainian National Security Bureau claimed that a total of 4 military airports in Russia were attacked, which is a special operation carried out by Ukrainian intelligence agencies. The Ukrainian side announced that 41 strategic bombers, including the Tu 95 and Tu-22 strategic bombers, were damaged.
Ukrainian President Zelensky also made a special video speech, admitting that the operation has been prepared for a year and a half, and a total of 117 drones were dispatched to carry out attacks. The Ukrainian National Defense Security Agency also released pictures and videos of related drone raids.

It is reported that the operation was coordinated by Zelensky himself and led by the Security Bureau Director Maliuk directly carried out. Drones are transported to Russia bit by bit by bit by bit by bit by bit by bit. Then, it is assembled and loaded into a van truck; before the operation begins, Ukrainian agents hired locals to drive the truck to a designated location near the airport; finally, Ukrainian agents are likely to have remotely used communication methods including Starlink and local Russian signals, activate and release the drone, and bring bombs to attack the Russian strategic bomb fighter parked on the runway.
Although Russia denied the outcome of Ukraine, saying that only a few strategic bombers suffered losses, the Russian army's losses were definitely not small, according to pictures and videos and other related information. Russia currently has about 50 Tu-95M strategic bombers, and dozens of Tu-22M.

If the Russian Aerospace Forces really lose 41 strategic bombers, not only will the Russian-Ukrainian conflict battlefield, the long-range strike capability will be greatly reduced in the short term, but also may be affected in other strategic directions, such as the strategic cruise to Alaska, the United States.
And it should be noted that these four attacked airports are all in the heart of Russia, such as Murmansk, which is more than 2,000 kilometers from the Russian-Ukrainian border. I thought these places would be safe, but the facts proved that this was definitely a mistake in the judgment of the subspecies.
So, after the attack, when the Russian side held a meeting to study and discuss the response to the problem, it was said that Putin did not attend the meeting. Logically, such a huge loss directly affects Russia's strategic forces and the subsequent battle against Ukraine. Putin should also have to participate. But Putin's move also shows how big the problem this matter reveals and how bad the impact is, so that even the people are not in the mood to attend such an important meeting.

Although this year, the Russian army has an absolute advantage in the front-line battlefield. However, Russia has been repeatedly attacked. Before and after the raid on Russian airports, Ukrainian agents also carried out attacks on many bridges.
On the one hand, the special attack organization is indeed relatively successful; but on the other hand, it also shows that there are too many loopholes in the rear of Russia, which is no wonder that Putin is so angry.
