Did Obama send $1.7 billion in cash to Iran as Trump claims?

US President Trump defended the war in Iran, claiming military actions have severely damaged Iran's missile and drone capabilities and predicting the conflict will end within three weeks. Trump criticised former President Obama for the $1.7 billion cash payment to Iran, which was actually a settlement of frozen Iranian assets from the 1970s, not a direct payout. Trump argued the military campaign is shorter than previous US wars and necessary for national security, urging Americans to keep the conflict in perspective.
