Conservatives can multi-task.
It is not in the security interests of the US to allow an avowed enemy of the US, trample over weaker nations.
Appeasement begets more Russian land grabs. We can make them pay an economic price, Russia has already pushed all of Europe closer to the Western sphere.
It’s not about multi-tasking. The point I was making was that a lot of neoconservatives seem to care about the integrity of every border and the sovereignty of every nation except that of the US. The same people (John McCain, Bill Kristol) who are all up in arms about Crimea are the ones advocating policies that amount to an annexation of the US southwest by Mexico in everything but name.
