What, they're going to raid every Caribbean island nation? Many of those island nations have large sums of liquid assets sitting in offshore financial centers and given their banking secrecy laws that are tighter than even Swiss law, it'll be kind of hard to grab that money.
The swiss buckled to the IRS and the fedgov, the Caribbean countries will fold like a cheap suit under fed pressure.
The only safe accounts are those of fed bureaucrats and their business cronies. Everyone Else's money is fair game.
Don't forget, when the fascists take over the US, anything goes, and nobody is safe.
