I know quite well about false flags. but do you seriously believe an Iranian official will publicly come and say " yeah it was us" ?
you give subtle clues. like your media being the first to report it. having senior officials who are normally diplomatic give out open threats, and Iran openly saying if we cant export oil no one can.
the americans and Saudis and UAE have plotted to take Iranian oil off the market, and pump out oil of their own to try to offset it. this policy depends on Iran sitting on its *** and seeing its export capacity be limited to the "grey" market while its enemy nations are going right thru Irans door taking away Irans revenue.
Iran is the major power of the region and the guarantour of security for the Persian gulf and straight of hormuz ( as much as the US wants to think its them). Iran simply cannot sit by and let this happen.
if Iran cant export oil, expect many more arab tankers and oil infastracture to get blown up. Btw. on totally unrelated news, the houthis magically got their hands on a serious cruise missile that hit a Saudi air port (but can also probably hit vital oil infastracture and possibly desalination plants)
let the escalation begin.
