I think you have some faulty assumptions here.
Israel is very reliant on US support to be sure, but not totally reliant on us. They have their own military industrial complex and could ramp that up if needed, they have their own nuclear program, they would certainly have to scale back in some aspects, but I don’t think there’s much that we can do that would stop the war in its tracks. They’d change tactics, and Israel can be very creative, look at the recent pager bomb thing.
That’s not saying that we should continue supporting them and sending them supplies. I just don’t think it would be the quick end you’re thinking it would be.
If they knew the US wasn’t going to step in, we might see other countries, Iran perhaps, step up their involvement. If Israel starts getting desperate they might do some incredibly stupid things, like using those nukes, their mindset seems to very much that if they think they’re going down they’re going to take as many people with them as possible.
There is basically no chance you’re going to be able to land that boat at any port in Israel/Gaza and let 10k people loose. You’ll be stopped at the port if not even sooner, I’d honestly be a little amazed if you even be allowed to set sail in the first place.
While hamas is overall arguably on the right side of this conflict, don’t mistake that for meaning that they are an overall good organization. 10k Americans would make for some damn good human shields and hostages and they’d snatch every one of you up that they can. It’s not going to be as simple as just chilling in Gaza clogging up streets so Israel can’t get through (assuming Israel doesn’t just decide that your enemy combatants too and wow you down) you’re probably just as likely to end up as a Hamas prisoner and spend months or years in some pretty terrible conditions hoping for rescue.
And the idea that you’re going to get 10k to sign on is pretty laughable, I’d be amazed if you could get 100.
I’m just scraping the surface with a few thoughts off the top of my heads.
So ignoring the technical problem of how it could actually be done, let’s assume we somehow did it, cut every cable, and somehow blocked every cell tower and satellite from somehow connecting to North Korea to the rest of the world.
For the average north korean citizen, probably nothing much changes, most of them don’t have much access to the internet to begin with.
For those who do, the elites, people in university, those government, military, etc. it will probably worry a bit.
For the elites who get to enjoy the internet as a luxury, probably not too much changes. I doubt that except for maybe the very top echelons of DPRK society, the Kim family for example (and maybe not even some of them,) anyone is getting totally unrestricted access to the global Internet. They’re probably limited to mostly a bunch of north korean-hosted websites, and unless they’re relying on data centers and such abroad (and they very well might be,) there’s not really much we can do to take them down unless we really want to go in and attack all of the internal Internet infrastructure.
It’s going to hamper their universities and such, sucks for them, probably no great loss for the world, the next big scientific break through probably wasn’t coming from the hermit kingdom anyway.
It will definitely hurt their ability to conduct espionage, cyber attacks and such, that goes both ways though and it also makes it harder for other countries to spy on them.
They will do their usual sabre-rattling in response, maybe even going a bit above and beyond their usual mostly empty gestures, but probably nothing that’s going to lead to any actual escalation p
