But let's just look specifically at Israel's policy on food aid. All 2.1 MILLION Gazans are facing food insecurity right now, and 60% of them (~1.3 million) are facing CATASTROPHIC levels of food insecurity (ipcinfo.org/ipc-country-analysis/details-map/en/c/1157985/). The GHF, which the UN consistently warned was not being properly thought through to deliver sufficient aid, has in fact not helped stem the tide on Gaza's famine-level conditions (the first archived article I linked).
The reason your article says the GHF is the "only functioning aid delivery system in Gaza" is because Israel has made it difficult for other aid groups to get aid in. For instance, any internal movement in Gaza by these aid groups has to be approved by the IDF (for example, "we would like to drive to Rafah")--only around 1/4 of these requests were approved (same link). And while it's certainly plausible that Hamas is targeting GHF workers, the fact that Israel's military action has killed over 450 aid workers (unocha.org/publications/report/occupied-palestinian-territory/humanitarian-situation-update-292-gaza-strip) has certainly had a far bigger impact. And Israel has multiple times struck aid groups that had "done everything right" and coordinated with the IDF (https://shorturl.at/IXqBR).
And yes, aid trucks are very commonly looted, but surely, SURELY, in a place where over a million desperate people are on the brink of DEATH from starvation, we can't chalk this all up to Hamas, which Israel has, I'll admit, weakened quite a lot.
I just don't see how failing to get food into Gaza as urgently as possible helps defeat Hamas. And let me remind you that in the long run, desperate, embattered, and devastated people are far more likely to seek violent instead of diplomatic resolutions. Just imagine how you'd react if a coworker you don't like came to your house, killed your parents, and then took all your food (again, ignoring a long history).
As for Israel "trying for peace," I have extreme concerns about Israel's commitment to any two-state solution. "The Knesset declared its opposition to the establishment of a Palestinian state west of the Jordan River... This resolution effectively removed the concept of a Palestinian state from the agenda." (jpost.com/israel-news/article-862007). And the state seems intent to keep expanding (illegal) settlements in the West Bank... (bbc.com/news/articles/c1j5954edlno)
