If you think Russia/Putin attack on Ukraine is of no importance to US, then you are seriously lacking in imagination. Failure of us to support Ukraine will immediately signal to China they can move forward on Taiwan attack and against the countries around the South China Sea. Anyone remember what happened to us on Dec. 7, 1941, because people didn’t think what was happening in the far east concerned us. In your comment, like many, you raise the old we can’t walk and chew gum trope.
You are full of BS. Ukraine is not in our national security interest, never was, and likely won’t be. Sucking up our money and resources to fight a proxy war with Russia, the Ukraine and Russia Civil War, is a waste. The Palestinian Hamas pogrom in the Middle East is our concern. Americans are dying, being raped, and taken hostage at the hands of these barbarian Islamists. It is my opinion that we should declare war on Hamas and kill every last one of them. As for Taiwan, the power of our commerce will hold China at bay, plus our nearby, Navy. The only requirement we need is the willingness to cut off all commerce from China, that will quickly shut them down. Make clear they risk that and they will not attack.
