Nobody is going to initiate a boots-on-the-ground invasion of Iran, which is what it would take to actually bring down the current regime.
So far there has been a concerted effort to destroy Iranian military assets, plenty of destruction of infrastructure, they even managed to kill a fair proportion of the regime's leading figures, but as of yet, there is precious little sign the regime is anywhere close to throwing the towel in.
Trump's attention is already wandering toward Cuba, so I expect before much longer there will be some return of US naval groups to the Caribbean and this entire thing will fizzle out. The regime will remain in place, and all that will have been achieved is Trump and his cronies will have enriched themselves again due to market manipulation, and the US military/Industrial complex will benefit from this latest depletion of inventory.
As already mentioned, anyone who thinks Trump is doing any of this for the benefit of Iranians, or indeed, actually gives a single shiny shite about Iran, it's people, or removing the regime, is delusional. It's entirely about money, his ego, and deflection from his calamitous failures and domestic unpopularity.
I wouldn't be booking a holiday to Cuba any time soon.
