Yes Virginia, resettling 1.8 million Arabs isn’t a difficult task.
Granted it might be hard to get a country to take Arabs who sympathize with and harbor terrorists, but moving them shouldn’t be a problem.
India and Pakistan both resettled millions. After WW11 the allies removed three million Germans from Sudetenland. So if that could be done all those years ago, shouldn’t be an issue today.
And after Gaza is rebuilt the ones who were totally vetted could return on a trial basis.
