Building a port facility in hostile territory from the sea is the kind of d-day scenario that the US military will train for and have some kind of plan for. I don’t know how the 60 day figure came to be, but that’s almost certainly not how long it takes to actually construct a usable facility once the resources have been committed and are on the scene.
Israel is a long ways away from the Caribbean and central America, where the CIA had the most success with that stuff, thanks to the Monroe doctrine.
I don’t think it’s that easy to get what you want in the Middle East.
