Israel has imposed a partial siege on the Palestinian Gaza Strip since 2007, when a coup attempt against the elected Hamas government failed. UNCTAD estimates that the Israeli occupation costs the Palestinians of Gaza about $16.7 billion per decade, so by 2027 that would be $33.4 billion. The difference between a decent life and crawling on trash hills to find the wherewithal to live. Elements of the siege constitute war crimes. As for the exodus of Palestinian youth, that has been hailed as a goal of Israeli policy by right wing members of the Israeli parliament. Unfortunately, since Palestinians are kept stateless by Israel, they are not wanted in most countries, and those who leave often find a watery grave in the Mediterranean or end up undocumented and with blighted lives abroad.
