Politico leads with a diplomatic piece exploring President Barack Obama’s goal to jump-start multilateral discussion on nuclear security; specifically the difficulties Israel presents to any future  summit on nuclear terrorism prevention.

Side-notes—Obama has yet to visit Israel; former Bush administration U.N. ambassador John Bolton offers this up to The WSJ:

Relations between the U.S. and Israel are more strained now than at any time since the 1956 Suez Canal crisis. Mr. Gates’s message for Israel not to act on Iran, and the U.S. pressure he brought to bear, highlight the weight of Israel’s lonely burden.

Striking Iran’s nuclear program will not be precipitous or poorly thought out. Israel’s attack, if it happens, will have followed enormously difficult deliberation over terrible imponderables, and years of patiently waiting on innumerable failed diplomatic efforts. Absent Israeli action, prepare for a nuclear Iran.
