In an extraordinary mea culpa on Iranian state television Saturday, the commander of the unit responsible said "I wished I was dead," when he realized that what his unit thought was a cruise missile was actually a plane.Ukraine is demanding a full investigation and compensation for the victims — mostly Iranian, Canadian and Ukrainian — who died when the airliner was shot out of the sky, hours after Iran launched a number of missiles at two bases housing US troops in Iraq.Related: US unsuccessfully targeted another Iranian military official Now what? How are the families of the passengers and crew compensated for this unbearable loss? And how do US and Iranian government leaders, now in direct and open military confrontation for the first time since Iran's Islamic Revolution, map a route out of this crisis?There are still many unanswered questions about the evidence of "imminent and sinister attacks" against Americans that led the US to kill General Qasem Soleimani last week. Republican senators, Mike Lee and Rand Paul, joined Democrats complaining about the Trump administration's briefing to Congress. Lee called it: "The worst briefing I've seen — at least on a military issue — in my nine years."Congress also wants to know whether Soleimani was targeting four US embassies before he was killed, as Trump told Fox News on Friday. It will also seek to find out if the US's aim was broader. On the same day the US killed Soleimani in Baghdad, it tried unsuccessfully to kill another senior Iranian military official in Yemen.In the meantime, the latest USA Today poll since these hostilities started, say Americans do not feel safer since Iran's top general was killed.The poll found that 55% of Americans say the killing of Soleimani makes the US less safe, while 57% oppose the threat of US airstrikes on Iran's cultural sites and 53% support Congress limiting Trump's ability to order military strikes. Elsewhere, anti-Americanism has soared around the world since Trump took office, according to new Pew research published Wednesday.The US's European and NATO allies do not support Trump's latest strikes on Iran, nor pulling out of the Iran nuclear deal. It's notable that Germany's Angela Merkel went to Moscow Saturday to visit Russian President Vladimir Putin to try to defuse the current crisis. She did not go to Washington.So, is the crisis between Iran and the US over? No, it is not.President Donald Trump has announced a new raft of sanctions against Iran. He said in his address Wednesday that, "the US will immediately impose additional punishing economic sanctions … these powerful sanctions will remain until Iran changes its behavior. In recent months alone, Iran has seized ships in international waters, fired an unprovoked strike on Saudi Arabia and shot down two American drones."Related: How Pompeo convinced Trump to kill Soleimani and fulfilled a decade-long goalHe called on Europe and Russia and the rest of the world to pull out of the Iran nuclear deal, while also calling on them to join him in making a new deal with Iran."We must all work together toward making a deal with Iran that makes the world a safer and more peaceful place," Trump said. "We also must make a deal that allows Iran to thrive and prosper, and take advantage of its enormous untapped potential."The extraordinary direct military confrontation between the US and Iran may be over for now, but Iranian leaders are pushing their longtime political agenda.In his televised address on Wednesday, Iran's Supreme Leader Ayatollah Ali Khamenei insisted: "Military action this way, that's not sufficient. What matters is that the presence of America … that should come to an end."And the more moderate President Hassan Rouhani, who was elected in 2013 on his promise to negotiate with the US and improve Iran's relations with the world, backed up Khamenei's message in his own tweet.Also on Wednesday, in his address to the nation, Trump made remarks that seemed to indicate he too was looking for ways to reduce the US military presence in the region.
