Over at Slate, Fred Kaplan makes an excellent case that conservative ire over Barack Obama's visit with Hugo Chavez is misplaced. Here's the core of Kaplan's argument:
The shockwaves over the handshake might best be explained as a hangover
from the long years of George W. Bush's presidency, when dealings with
those who disliked us were expressly forbidden, out of a vague fear
that such contact might debilitate us or legitimize them.
