The landmark US defense aid package signed on September 14 is an important event for Israel, for three reasons. First, it indicates the depth of the American leadership's commitment to Israel's security, despite differences of opinion between the two countries. Second, it allows the IDF to sustain its multiyear plans to bolster capabilities in every field. And third, it signals to all those plotting against Israel in the region and the world that Israel's friendship with the US remains strong.
