The article is about Israel waning to attack Iran. Israel doesn't want to attack Iran by themselves they want the United States to help them. “It says an attack by the United States could set back Iran’s nuclear program four years at most, while a more ambitious goal — ensuring Iran never reconstitutes its nuclear program or ousting the regime — would involve a multi-year conflict that could engulf the region. Yet Prime Minister Benjamin Netanyahu of Israel is trying to browbeat President Obama into a pre-emptive strike. On Tuesday, he demanded that the United States set a red line for military action and said those who refuse “don’t have a moral right to place a red light before Israel.” Later, Mr. Obama telephoned him and rejected the appeal. On Friday, Mr. Netanyahu suggested in an interview that Israel cannot entirely rely on the United States to act against Iran’s program” (Editorial). The reason why Israel needs the United States is because Iran is advancing its nuclear program and that puts Israel in danger.
So Israels best chance at keeping Iran away from them is to join an alliance with the United States and other strong major powers.
