I do think Obama is slowing going in the right direction. Saw on various news sites that we are stepping up exercises with NATO, we've sent some military units to the baltic states, we're supporting Ukraine financially and no doubt in other ways. I think we can do more economically, politically, and militarily to deter him. The sanctions we placed on them so far are a joke, maybe it's just a delay tactic until we can coordinate deeper sanctions and economic retaliation. We should give Israel the green light to do whatever they want in Syria and Iran, with US support. We can send troops in to Poland and other baltic states not just for exercises.
Whatever we do, we need to make it is substantial and sudden. Phasing things in will not work. It sucks, and it's brinksmanship, but it is necessary. Otherwise world order will break down and the effects of that will be incredibly damaging, and long lasting, not just for the US, but for every country. Putin has led us to this return to containment and brinksmanship.
