Israel is a nuclear power.
Whatever the Palestinians can do against is in retaliation to the annexing of their land, the ghettoisation of their people, the control of essential goods, the regular military incursions into their territory, the destruction of their houses, the systematic killing of their people - including the use of chemical weapons on built-up areas, hospitals, schools, nurserys..... and all the other atrocities committed in the name of 'The Promised Land' ranks a little insignificant against wishing that 'Israel has no right to exist'.
In those circumstances, I'm afraid I might wish for the same thing.
