> The idea that, if it weren't for UNRWA, there would be no more refugees because they'd all have gone back home or been peacefully resettled elsewhere, is absurd

And yet this is exactly what the UNHCR does. A refugee settles, and they are no longer a refugee.

> To suggest that they are the ones creating the sitution

You're arguing against a strawman. The Arab war on Israel in 1948 created the refugee crisis. No one argued any different.

There is evidence that UNWRA is perpetuating the situatiyon, your personal incredulity notwithstanding. This is but a single example, but it is enough to demonstrate that they intentionally exacerbated it. https://www.timesofisrael.com/unrwa-textbooks-still-include-...
