Nixon and Kissinger never went on trial (although they should have for their secret war in Cambodia and Nixon for his part in the Watergate cover up) but some of their henchman did and a number of them wound up with prison terms.

The American people would never sit still for an alliance with a bloodthirsty thug like Assad or even Putin. We do have a sad history in the previous century of propping up corrupt tyrants but Assad's atrocities are just too well documented.

For my part I think we should get out of the middle east and Afghanistan post haste. 15 years of war is more than enough. At this point we're just inspiring more enmity towards us and boosting the recruiting efforts of various terrorist organizations. The only involvement we should have over there is to provide humanitarian aid. Time to let Israel shift for itself and to move away from our dependency on fossil fuel.
