Here is former Sen. Joseph Biden, now V-P of the U.S., threatening in 2007 to impeach George W. Bush if he attacked Iran without Congressional approval.
But now he, and Obama, have done just that. They have attacked Libya, who is no "immediate threat" to the U.S., without going to Congress and asking for the authority to do so.
Did you notice how the Democrats cheered for Biden's threat against the "bad cowboy" George W. Bush? But now many of those same Democrats are very likely making excuses for Obama-Biden as they wage blitzkrieg in Northern Africa and Central Asia.
It is hypocrisy to pretend to be a peacenik only when the other party is in power. Real peace movement activists oppose war no matter which party is dropping the bombs. Anything else is just blind obedience and servility.
It is situations like this that are killing the Democratic Party with the thinking public. Over and over again we see examples of "say one thing" but "do another".
My mother always used to say, "What's good for the goose is good for the gander." In Washington DC that doesn't seem to apply.
