In order for the American president to do anything, domestic and foreign, he must have legal authority, or at least the facade of such. NATO membership is that legal authority. It mean since Ukraine is not a NATO member, we cannot DIRECTLY help Ukraine. Sympathetically, the American people stands with Ukraine, but legally speaking, and I know how it sounds 'hiding' behind the legality shield, the American people are tired of sending troops to foreign lands and fight with little or no national security interests.
What we can and will do is help Ukraine INDIRECTLY via the porcupine policy, or a repeat of the Soviet occupied Afghanistan policy. We will send sophisticated weapons to the Baltic countries who will send the weapons via land routes to Ukraine. We should have done this earlier but it is not too late to arm the Ukrainians enough to make life difficult for the Russian occupation.
Been busy. I recently moved from the Wild Wild West part of the US back to the east coast nearer to my family. So I have been busy spending time with my little niece and nephew.
