WASHINGTON — Tensions rising by the day, the Obama administration said Friday it is warning Iran through public and private channels against any action that threatens the flow of oil from the Persian Gulf.
Spokesmen were vague on what the United States would do about Iran’s threat to block the strategic Strait of Hormuz, but military officials have been clear that the U.S. is readying for a possible naval clash.
That prospect is the latest flashpoint with Iran, and one of the most serious. Although it currently overshadows the threat of war over Iran’s disputed nuclear program, both simmering crises raise the possibility of a shooting war this year.
“We have to make sure we are ready for any situation and have all options on the table,” Defense Secretary Leon Panetta said, addressing a soldier’s question Thursday about the overall risk of war with Iran.
The U.S. still hopes that international pressure will persuade Iran to back down on its disputed nuclear program, but the Islamic regime shows no sign it would willingly give up a project that has become a point of national pride.
A bomb, or the ability to quickly make one, could also be worth much more to Iran as a bargaining chip down the road.
