Yes, OUR government does fund Iran. Read about the Iran Nuclear deal under Obama, we gave them billions, more than we have given Israel.

That's an extraordinarily loose definition of "gave"
To add context: the funds were not “given” as one might give humanitarian funding. The funds were Iranian financial assets that were frozen after the Iranian Revolution, accrued interest over the subsequent decades, and were returned as part of a legal settlement. I stake no position on whether this should have happened, just providing more specific color to the situation.
