Joe Biden has big troubles with Putin. It's his own fault. When Trump sanctioned companies doing business on the undersea Nord Stream pipeline from Russia to Germany construction came to a halt. Guess when the construction started back up. Just 3 days after Biden took office. Because they knew how soft Biden would be on it.
There is already a pipeline from Russia to Germany. Why did Putin not fully invade Ukraine in 2014? Because the Ukrainians could easily destroy the portion of the current pipeline which runs through their country. Putin backed off before they did that.
So why is Putin so eager to invade now? Because Joe the idiot Biden took the sanctions off Nord Stream. That pipeline goes around Ukraine. So Putin is no longer concerned about the Ukrainians destroying the current pipeline.
Biden has to put the sanctions back on Nord Stream. Once the pipeline is built it will be too late.
