What I do think is that Jews world wide will unfortunately not be safer as a result of Israeli actions in Gaza.
Until the interconnected-ness of the two is full accepted by both sides and oppression ceases the violence will never end.
By its own yardstick, Israel has totally failed in Gaza, and almost certainly succeeded in creating thousands more people who hate everything Israel stands for, thus perpetuating insurrection for ever more.
Look at the Mau Mau in Kenya and the Vietcong all as a result of long and continued oppression. Terrible atrocities were committed by a people whose reaction to no freedom and oppression was like a coiled spring.
People need to be free.
