That is crazy.
There is only one way to understand your use of "idealism." To you it means killing people for ideals (this also explains how you can imagine that Bush believes in Democracy and freedom in spite of the fact that he also believes he had the power to lock up anyone anywhere indefinitely without trial (and did so).
I generally respect you and the only complaint I usually have with this blog is that you don't post enough. But your definition of idealism convinces me that your inner idiot -- the one which advocated invading Iraq, still lives. You now understand that that decision was insane, but you stick to the insane idea that idealists who don't kill don't count.
If you don't equate idealism with a form of killing, then why did you write the passage I quote ? I ask for information. I think you can present no other explanation.
Note I am not a pacifist and agree that sometimes our ideals require us to kill people. The reason I am appalled is that you don't seem to think anything but killing could ever be the result of ideals.
Of course it is also clear that you think that foreign policy which doesn't involve killing people amounts to nothing.
Also the subtitle is garbled.
Chait's claim is that Obama is a realist but not a Realist, so this is an error "What Is Obama’s Foreign Policy Ideology? Realism — not the same thing as realism!" it can be corrected to "What Is Obama’s Foreign Policy Ideology? Realism is not the same thing as realism!" or to "What Is Obama’s Foreign Policy Ideology? realism — not the same thing as Realism!
Finally, as written it is equivalent to writing "It is realism - not the same thing as realism" The capital R in the subtitle just indicates that the word is the first of the sentence. An irregular single r as in my second correction is meaningful. Capitalizing the first word in a sentence indicates nothing.
