I'm not saying people actually agree with destroying Yesha (although a lot of sick Israelis do), but the fact of the matter is that most Israelis are secular and do not have a personal faith that G-d will sustain the nation through all things. Even if they are right-wing in principle, they really do not think Israel can overcome all of this world pressure on its own and they have been brainwashed to believe that U.S. aid is necessary for their continuing to exist.
