If the United States or western countries station troops in Ukraine, what kind of reaction might Russia have?

At present, the relationship between Ukraine and Russia has reached the point of explosive. Now that the United States has stationed troops in Ukraine, it has expressed its support for Ukraine. Russia has also stepped up its patrols, prepared cruise ships and prepared for the worst.

The world situation will never be calm. The North Korean nuclear issue in Northeast Asia has just been resolved, and the Middle East has begun to be restless again. At the same time, the long-silent Ukrainian-Russian problem broke out again and became more and more serious. Although Ukraine has been trying to get close to the West after "breaking up" with Russia, this time the Ukrainian government directly proposed and invited the United States to station troops in its country, hoping to gamble on national luck and hold the US thigh against Russia. This revision is also aimed at narrowing the distance with the West and obtaining the qualification to join NATO and the European Union. This undoubtedly touched the bottom line of Russia.

Three Ukrainian naval vessels crossed the Russian border and entered Russian territorial waters, intending to cross the Kerch Strait into the Sea of Azov. As the Ukrainian side did not listen to the Russian warning, the Russian border patrol boat took decisive measures and collided with a Ukrainian tugboat, causing the tugboat to be seriously damaged and unable to move forward. It also opened fire on Ukrainian patrol boats, causing three Ukrainian personnel to be seriously injured and sent to the hospital for emergency treatment. The rest were arrested after Russia took control of the situation, and all three Ukrainian ships were detained.

Russia not only dealt with the incident quickly, but also blocked the waterway quickly, dropped an oil tanker on the Kerch Strait Bridge, and sent drones, patrol boats and helicopters to conduct uninterrupted regional patrols to prevent the situation from deteriorating. Russia has also deployed three aviation regiments nearby, which shows that Russia has prepared for the worst.
