If you follow current events at all, you will know that President Obama has adopted and expanded all of the so called, cowboy, "shred the Constitution" policies of the Bush Administration--signing statements, drone attacks (now against an American Citizen) Gitmo, invading Libya.
The left was apoplectic over Bush and completely ignores Obama. Frankly, this show of hypocrisy is what I enjoy most about the Obama administration.
Now it appears that the US and Israel are killing Iranian Scientists. Here's an interesting article about the killings and about the silence of the left.
What’s most remarkable here is to compare the boisterous, furious denunciations of the mere suggestion by a blogger on the Internet that Iranian scientists be killed, versus the relative silence in the face of its actually being done in real life, now that the corpses of murdered Iranian scientists are beginning to pile up. Does anyone doubt that some combination of the two nations completely obsessed with Iran’s nuclear program — Israel and the U.S. — are responsible?
