Biden didn't "cause inflation". The inflation was the result of covid and it was worldwide. Trump had a lot more to do with causing the inflation since he signed a deal with OPEC after he lost the election, to cut oil production and raise oil prices.
The deal will reduce output by 9.7 million barrels a day. While significant, the cut falls far short of what is needed to bring oil production in line with demand.

Furthermore, the USA had lower inflation than Europe, and Biden brought the inflation down faster than any other nation in the world.
That's what we've been hearing for decades. The Agreement that Obama signed in 2015, and which the Iranians were in compliance with, prohibited them from enriching uranium for 10 years.
If, and it's a big "if", the Iranians are "close" to having a nuclear weapon, it's only because Trump let them do it, when he tore up Obama's deal.
