More lies, Teribus. During the time that this money was being given in aid to the Palestinians, hospitals, schools, roads, universities, and other important and badly needed civil infrastructure was built. Some of it went toward the security apparatus, but that was required of the PA by the agreements that the Palestinians made to police their own people on behalf of Israel. This civil infrastructure is mostly non-existent today, but that is because it was destroyed by the government of Israel.

Israel has not ever honored its agreements with the Palestinians, nor does it have any intention of ever doing so, no matter what the Palestinians do or don't do. During the period when Israel was obligated to stop building new settlements, it not only continued to build them (and expand existing ones), it even increased the rate at which it built them and expanded them. This is because it has never been Israel's intention to allow ANY Palestinians to remain on the land from which they originate. Israel's intention is, and has always been, to finish the job of ethnic cleansing (genocide) of the indigenous non-Jewish population that was begun prior to and during the 1948/49 war.

There is nothing the Palestinians can to do prevent this. The only way to prevent this from happening is for enough people to apply pressure to the governments of the US and Israel that it becomes impossible to continue with this agenda. So far there haven't been enough people applying pressure to make the needed changes, but the number of people who are doing this is growing steadily, and it will reach critical mass eventually. The only question is whether or not there will be any Palestinians left in Palestine when this finally happens. Either way, though, the world will eventually come to look with great shame upon what was allowed to be done to the indigenous people of Palestine (some of whom include the descendants of the original Christians), just as it has with slavery, the genocide of the indigenous peoples of the Americas, segregation in the US south, South African apartheid, and the Holocaust.
