So?
We give money to almost 100 countries, to serve our interests as we see them. What they do with the money would in many cases not meet with popular approval here, but, as you know, the US is not a democracy but a representative republic with foreign relations assigned to a Chief Executive and his government.
Our relations with Iran are bad, our government wants them to be better.
This may well be unwise, but there are many factors to consider, and the situation between Iran and Israel is only one of them.
Well,it’s complicated...no argument there.
