President Donald Trump will decide in the next two weeks whether the U.S. will get involved in the Israel-Iran air war, the White House said on Thursday, raising pressure on Tehran to come to the negotiating table.

In saying he'll make a decision on Iran within two weeks, President Trump has reached for an old standby. Two weeks and he’ll know whether Russian President Vladimir Putin wants to end the war in Ukraine.

In Tehran, the frequency of the Israeli strikes has completely upended daily life. The constant thud of air defense systems, the loud boom of explosions and the wailing sirens of ambulances and fire trucks have replaced the sounds of a metropolis typically buzzing with traffic, street music and the Muslim call to prayer.
