The Iranian choke hold on the Strait of Hormuz evidently had a lot to do with it. By cutting off roughly one-fifth of the world's oil supply over the past five weeks, Iran's blockade of that narrow waterway caused an energy crisis and fears of a global recession that the White House could not abide for long.
The conflict has driven up the price of oil and natural gas; damaged oil refineries, tanker terminals and other energy infrastructure; disrupted shipments of fertiliser that the world's farmers depend on; and damaged the confidence of businesses and consumers.
The E-3 Sentry, with its distinctive rotating radar dome, is a flying command center that allows American forces to see and coordinate the battlefield. In recent weeks, Iran destroyed one on a runway in Saudi Arabia and reportedly damaged another.
After 40 days of fighting, the United States and Iran agreed to a two-week ceasefire, with negotiations expected to begin in Islamabad. One key point in Iran's proposal is allowing shipping to resume through the Strait of Hormuz, which has been closed since the war began, causing global oil prices to soar.
The provisions of the Bahrain-led resolution had been repeatedly pared down in an effort to convince Russia and China to abstain from voting, an effort that ultimately failed as the two nations refused to back down in Tuesday's vote.
