The timing of this attack along with Russia turning its back on Israel and Sunni Saudi Arabia suddenly siding with Shia Iran points to Iran having nuclear weapons and the start of WWIII.
“Iran having nuclear weapons”
Iran clearly has the means of making nuclear weapons, maybe around a dozen each year.
The main limitation is a lack of reliable delivery means.
I fear an EMP. A single nuke in the US won’t ruin the country if detonated anywhere near ground level.
