Unfortunately for Israel, in the real world demographics also change maps.
You (pro-Palestinian advocates) seem to be operating under the impression that Israel will do nothing while this so-called Demographics Threat unfolds.
There is no threat from
within the present borders of Israel, if one omits the West Bank and Gaza from that definition.
If Israel decides to complete its Reconquista and annexes the West Bank and/or Gaza in perpetuity, it will forcibly evict and expel the Palestinians and then move Israelis into the vacuum to consolidate those new holdings.
Thereby removing the Demographics Threat before it ever materializes.
Encroachment upon the Rump (vestigial, remnant) West Bank continues apace and appears to be accelerating.
Nobody is going to stop Israel if it
does choose to go the Expulsion route; or, should I say, should they openly declare the obvious.
How do you figure Israel will be able to expel/kill 5-6 million people logistically?...
Expel, not kill.
Unlike the savages on the Palestinian side who have repeatedly sworn to drown the Jews in the Mediterranean, the Israeli side isn't anywhere near as bloodthirsty as their opponents, and would resort to simple (and far more humane) expulsion.
How to handle the logistics?
On the macro level...
Incrementally.
1. Find a place that will take a certain number; gratis, or for a price.
2. Solicit volunteers to move; including relocation, setup/fresh-startand compensation monies; keeping families together, and all of that.
3. Effect the move; protecting them against Fatah and Hamas vindictiveness along the way.
4. Move Israelis into the vacuum.
5. Rinse and repeat, as often as necessary.
That should take care of a very large percentage.
For those hard-cases who won't go on their own, despite generous settlement funding and relocation assistance - military action - 1% will die - 99% will survive.
The survivors are forcibly relocated, but paid the same Wergeld as all the rest.
No further claims against Israel would then be allowed.
Expensive as hell.
But far cheaper than allowing either an internal military threat or an internal demographics threat to destroy the resurrected State of Israel.
"...And, do you think the U.S. would stand by and allow what is perceived its client state by the rest of the world to commit genocide/ethnic cleansing?..."
Yes.
Because it won't be Genocide.
And even the ethnic cleansing -like aspect(s) of such an operation can be arguably and logically masked as what it truly is: Population Transfer.
Done properly - and faithfully reflecting what is actually happening - the outcome removes a savage, hostile, intransigent and belligerent population segment from the region, and, lacking close proximiity, old enmities will burn themselves out in a generation or two, and a modicum of peace will descend upon the region.
...If the US allowed it to happen, there would be serious negative economic consequences for America. Ever take a look to see how much the U.S. sells to the Muslim world..."
If we were overly worried about that, we would not have attacked Afghanistan...
If we were overly worried about that, we would not have attacked Iraq...
If we were overly worried about that, we would not be drone-bombing NW Pakistan...
Donor Exhaustion has set in, within the Muslim world, with respect to the Palestinians, and trashing their trade relationships with the US would be Bad Business.
"...The UN would impose South Africa style sanctions that the U.S. would not veto..."
Possible
Unlikely.
If the UN General Assembly failed to override the Security Council (UNGAR 377, 1950) to prevent the United States from launching an attack on Iraq in 2003, it's highly unlikely that it will do so over a progressive but controlled and well-funded and well-compensated mass relocation effort.
"...The EU, Israel's biggest trading partner would impose even stricter sanctions..."
Perhaps.
But unlikely.
Once they see that it is being done as humanely as practicable and that those displaced were being relocated and re-established elsewhere, with some considerable support.
Hell, the Euros are Westerners as well, and will be happy to see an end to this 100-year-old squabbling in their backyard.
"...I don't think you have thought this through."
Well, they say the Devil is in the details, don't they?
A hundred-and-one things to address during the course of any such contemplation, but, done incrementally, it's not only practicable but actually likely.
The logistics and military aspects of the thing are probably the easiest to address, on the macro level.
The real challenges are (1) finding places willing to take-in some percentage of the Palestinians, (2) mustering sufficient financial support for the undertaking from the global Jewish community and its friends, and (3) public relations and damage control once underway.
One need look no further than the non-viable, unsustainable and disconnected (non-contiguous) parcels of land still remaining under Palestinian faux control, to see that we're almost to that point already, and one does not need a crystal ball to predict what the next steps are likely to be, in connection with the foolhardy and intransigent Palestinians, should this next (and final?) round of negotiations collapse.
I have no clue whether any of this is going to materialize, but it is fast reaching the point where the Israelis are going to have to get 'radical', and some-such approach is far more humane than what their enemies have sworn to do to them, given the chance.
Comes a time, every so often, in the life of a nation, when your back is against the wall and you're obliged to say: "
This is what needs to be done. To the Devil with world opinion."
Now, whether Israel has reached that point yet with its Barbarian negotiating partners, well, only the Israelis can tell us that.
