I support Israel but I don't dislike Mustafa Barghouti. He's a moderate Palestinian, more civilized than most.
Anyway Israel has been on this earth for 61 years, and the Muslims look like they have exhausted every possible way to boycott, sanction and sabotage it. It will survive. Egypt has low-profile trade links with Israel, and so do Jordan and Qatar. Qatar suspended the links after the Gaza war. In a couple of years, they'll be back... That's just how things have been happening.
Even if sanctions were imposed on Israel some time from now, especially given how the United Nations agenda has been hijacked by Muslim countries with the worst human rights records in the world, I believe Israel will stand strong. Look at Iran, it's already burdened with three waves of UN sanctions and it's standing strong. Zimbabwe, North Korea, Cuba, Sudan... If Third World extremists can do it, why not Jews?
