April 1 is the anniversary of the actual establishment of the Islamic Republic in Iran. (No fooling.) And so far, only one nation seems to have congratulated Iran on this occasion - Jordan:
One really has to conclude that Jordan simply does not trust the United States to curb Iran's nuclear and geopolitical ambitions, and that King Abdullah has decided that he needs to play nice with Iran. If Iran/Syria/Hezbollah wins the Syrian civil war, Jordan will be on the front lines, and Abdullah knows a thing or two about surviving in the Middle East.
The King wished the Iranian leaders continued good health and the Iranian people further progress and prosperity.
Trusting the US to commit to helping its allies is no longer part of Jordan's calculus.
