And no mention of the fact that the only approved form of Sunni Islam in Saudi Arabia, the fundamentalist Wahhabi doctrine, is almost identical to the version of Islam espoused by the terrorists. Bringing up such awkward subjects would have upset his audience, and the last thing Trump wants to do is hurt people's feelings.
Iran, to hear Trump tell it, is the source of all the region's problems. "From Lebanon to Iraq to Yemen, Iran funds, arms and trains terrorists, militias and other extremist groups that spread destruction and chaos across the region ... It is a government that speaks openly of mass murder, vowing the destruction of Israel, death to America and ruin for many nations and leaders in this room ... "
Trump delivered this remarkable farrago of lies and half-truths two days after Iran, the only Middle Eastern state apart from Israel and Turkey to hold relatively free elections, re-elected President Hassan Rouhani, who has worked hard to reduce the influence of his hard-line opponents. He also signed the deal freezing Iranian work on nuclear weapons for 10 years, and he clearly has popular support for his policies.
The "militias" Iran trains and supports include those in Iraq that are fighting to free the city of Mosul from the clutches of Islamic State (they also have tacit American support), and the Hezbollah movement in southern Lebanon, which has been part of the Lebanese Government since 2005.
The Iranian Government does not "speak openly about mass murder", and the one Iranian leader who spoke about the eventual destruction of Israel (although he did not promise to do it personally) was Mahmoud Ahmadinejad. He was defeated by Rouhani in the 2013 election, and was banned from running again in the one just past. "Death to America!" was a nationalist slogan popular in the 1980s.
Iran, like most large countries, has many conflicting political trends, and with careful selection and enough ill-will you can find enough extreme and ignorant comments to demonise the country. But the Islamic Republic of Iran has never invaded anybody, and it does not support terrorist attacks against the West or the Arab world.
Trump has drunk the Kool-Aid. He has bought into a partisan Arab narrative whose theme is an inevitable (and ultimately military) conflict between Iran and the Arab world, and has all but promised that the US would fight on the Arab side in that putative war.
This is probably the stupidest foreign policy commitment any American administration has made since the decision 60 years ago to take France's place in fighting the "Communist menace" in Vietnam. Iran has almost as many people as Vietnam, it's five times as big, and it's mountains and deserts -- plus some very big cities.
Maybe it is inevitable that Sunni Arab leaders will see Shia Iran through the lens of their own fears and stereotypes, and start making self-fulfilling prophecies of apocalyptic conflict. Trump has no such excuse -- and "Principled Realism" is not really the right name for this policy. How about "Reckless Complicity"?
