Looks like bibi got Green light from the US during recent talks in KSA to cripple iranian nuke project.
There was a report some days back that IDF was preparing for possible US strike on the iran’s nuclear reactor before Biden takes oath and today they assassinated iran’s top nuclear scientist.
In addition, Trump retweeted report of NYT on the assassination which means Trump administration helped in this Op and Israeli sources also confirmed that they were behind the assassination.
it is very important to note that Trump is very pro Israel and this was the opportunity that bibi didn’t afford to loose!
I think the reason behind acknowledgement by Israeli sources is that Israel-US wants Iran to make a mistake so that they can justify military strike on iranian targets!
