Iran fired missiles at a United States base in Iran, but no casualties were reported. Trump addressed the nation today about last nights attack and suggested that those same missiles could have been paid for when Obama's administration sent billions of dollars to Iran.
However, there is no way for us to know if that exact money was used to pay for these missiles, so it must be treated as speculation.
What we can prove is that America did send Iran a lot of money during the eight years Obama was president. However, based upon fact-checkers who gathered more information on the nuclear deal, the folks at PolitiFact said this about the nuclear deal:
The agreement was promoted by Obama. But it included China, France, Germany, Russia, the United Kingdom and the European Union — not just the United States and Iran.
The deal resulted in Iran getting access to some of its own funds — assets that had been frozen — it wasn’t cash given to Iran by the United States.
And $150 billion is a high-end estimate and the one with the least evidence to support it. The high-end estimate from the U.S. Treasury Department in 2015 was $56 billion, and outside analysts believed the number could be lower.
Per the deal, the United States and other countries lifted the sanctions and the funds were unfrozen after nuclear inspectors verified in January 2016 that Iran was doing enough to curb its nuclear program.
Later on in the same article by Politifact, they said:
What is correct is that largely because of the U.S. involvement, the deal resulted Iran getting access to likely tens of billions of dollars of its own funds, and it’s unclear how they might be spent.
So by technicality, Iran did have access to money, but it may not have been ours and it is impossible for us to know what exactly they spent said funds on.
Regardless, Iran fired missiles at an American base and where they got the money from really doesn't matter.
Here is Trump's response and around the 1 hour mark, you can hear when he calls out Obama for sending Iran money.
At this point, it does not matter how Iran paid for missiles, but that Americans bind together and support our country and military in peace... or war.
