Conflicting emotions

There are times my heart jumps for joy:
---Organic gardens at the White House
---Shaking hands with Chavez
---Talking with Cuba again
And then there are those times that I just shake my head...
---Continued Iraq and Afghanistan wars
---Expanding the war into Pakistan
---Threatening to invade Eritrea
---U.S. boycotts racism conference, says it 'singles out' Israel

The United States is boycotting a U.N. conference on racism next week over a document that "singles out" Israel in its criticism and conflicts with the nation's "commitment to unfettered free speech," the U.S. State Department said Saturday.

This at a time when Israel stands ready to bomb Iran's nuclear sites

The Israeli military is preparing itself to launch a massive aerial assault on Iran's nuclear facilities within days of being given the go-ahead by its new government.
Among the steps taken to ready Israeli forces for what would be a risky raid requiring pinpoint aerial strikes are the acquisition of three Airborne Warning and Control (AWAC) aircraft and regional missions to simulate the attack.

If we want others to practice diplomacy shouldn't we and our "allies" be expected to lead the way?
