Fred Kaplan takes the Senate Armed Services Committee to task:

Not to sound like a Golden Age nostalgic, but there once was a time when the members of the Senate Armed Services Committee prided themselves on having an understanding of military matters. They disagreed in their conclusions and sometimes their premises. But most of them worked to educate themselves, at least to the point where they could debate the issues, or ask questions of a general without coming off like complete idiots. The sad thing about this new crop of senators—especially on the Republican side—is they don’t even try to learn anything; they don’t care if they look like complete idiots, in part because their core constituents don’t care if they do either.

Drum is dumbfounded:

So why are Republicans doing this? I can’t quite figure it out. Is it a pure pander to the Israel lobby? A way of ginning up the tea party base? Revenge against Hagel for betraying them? Knee-jerk opposition to anything Obama wants? An expression of sheer, uncontrollable rage?
