Trump is running out of options. And the ones he does have left range from bad to worse.
If he walks away now, it's utter humiliation. He's wasted God knows how many billions, lost 13 KIA and hundreds wounded, and achieved nothing of value. Iran still has a stranglehold on the Straits, Israel, KSA etc have taken hits and Trump has not only burned his bridges with European allies but urinated on the ashes. Iran will be able to claim, truthfully, that they defeated the Great Satan. Other terrorist groups will rush to align themselves with the IRGC. It will be the greatest victory for Islamic terrorism since 9/11 itself.
If he invades Kharg Island, the number of Americans killed and wounded so far in this conflict increases exponentially. Depending on how long they stay there, casualties could well outstrip Afghanistan. And even if they take and hold the island, that still doesn't mean they'll be able to keep the Straits open for business. The kind of loss of blood and treasure is a non-survivable wound politically speaking. Trump would be lucky if he made it to the Mid-Terms without the 25th Amendment being invoked. Given what an utter cluster fornication he's made of this, it would be difficult for even the GOP to argue he wasn't unfit for office.
Trump ups the ante and destroys Iran's critical infrastructure such as desalinization plants etc? Not only is that a war crime - and yes, I know Trump doesn't care about that - but Iran will almost certainly retaliate by hitting similar targets across the Middle East. And the USA will have lost whatever tiny sliver of moral authority it has left. Oh, and we would certainly see another uptick in terror attacks across America and Europe. As well as sabotage against CNI carried out by organised crime proxies paid by Iran.
I was going to rule out insane decisions like a full-scale invasion of Iran, or even the limited use of nuclear weapons...but at this point Trump's so far off the reservation I'm not sure even he can guess his own next move.
In short, this won't end well.
