Dissidents are being hanged in Iran as we write this.
Israel has claims of self defense after being brutally attacked. The US has claims of wanting to take down the regime and prevent them from getting nuclear weapons. You can argue about claims and actions. The Iranian regime has no shred of excuse other than their total lack of humanity.
