This affair started in 2019 when -
* the Democrats made a hero of the Iran leader of terrorism activities in Iraq, Syria and Yemen when he was killed while in Iraq busy with planning further attacks on the US Embassy and other US interests in Iraq and the mourned the killing of the terrorist leader making a hero of him; and
* Kerry - representing the Democrats informed Iran that the Democrats will support the re-instatement of the Nuclear Treaty, butt also using that opportunity to inform the Iranian Foreign Minister of the involvement of Israel in attacks on Iran surrogates fighting in Syria - thus betraying Israeli secrets to the Iranians and in fact was active in undermining Israel.
However, Israel is now under a severe rocket attack with rockets provided to Hamas and that was made possible with money gained by Iran when the Nuclear Treaty was implemented, The money gained was not used by the Iranians for the betterment of the Iranian people - but to fund proxy wars in Syria, Iraq and Yemen and now also for the rockets raining down on Israel.
The Biden is already moving to get the Nuclear treaty re-instated and the situation in the ME will be further destabilized by their stupidity, They will no doubt send Kerry back to Iran and he will tell the Iranians how to get past the systems used by the Israeli's against rocket attacks to get into their favor,. The other alternative is to blame Russia for the total failure of Biden policies in the ME, as is normal when the Democrat policies misfired and have unforeseen consequences.
