We have no vital interest in Ukraine; by arming them we are inviting a response from those we help kill.
Within a few miles of me are two sites destroyed by pro-German saboteurs during (but before our entry into) WWI (Black Tom Island and the Canadian Car & Foundry Co.); they rightfully knew we were violating neutrality when arming their foes while abiding by Britain’s blockade of the Central Powers.
We - the people - have no vital interest in Ukraine. But corrupt 'elites' of the world from George Soros, Joe Biden, John Kerry etc etc etc... and probably half the democrats in DC DO have vital interest.
And 'elites' are willing to risk war and our lives to keep the place they launder their money - open.
