Memo to Biden, Blinken, Sullivan, Obama and Rice: How have those Billions to Iran work out?

Was it $10 billion (I have trouble figuring out how much) did the Obama and Biden Administrations give to Iran? How many billions in oil revenue has Iran amassed because you lifted the Trump sanctions on Iran? Where did the billions go? Hamas? Hezbollah? Houthis? Getting dangerously close to building a nuclear bomb? Building missiles? Sending soldiers into Lebanon and Syria? Sending missiles to Russia? Certainly not into improving the quality of life of the Iranian people! How has loosening the sanctions on Iran worked out? How was lifting the Trump sanctions on the Houthis worked out? How have the restraints on Ukraine left Ukraine in a worse military position? Why do you believe sanctions, much less weak sanctions, will affect the behavior of tyrants and terrorists? How have the pressures on Israel help bring about a settlement and release of the remaining hostages? How has allowing Russia to complete the Nord Pipeline while cancelling the Dakota Pipeline help secure peace in Europe? How’s that cozying up to Russia working out? Have you ever admitted a mistake in your major foreign policy decisions? Have you learnt anything from your mistakes?
