Where I can't help being curious is in the manner the US is supposedly helping Ukraine fight the war. Are they scared of Russia's action if they openly suport the war or is there something else they are guarding against? Your thoughts...
It's the same reason why the U.S. was not willing to put a no-fly zone back in March, they don't want to escalate. They're satisfied with a war by proxy. It's what the U.S. has been doing with Russia in the middle east for years as they were dealing with Bashar al-Assad. As long as they don't escalate with a direct declaration of war, war by proxy seems to be a winning strategy.
