Assassination is quite a good policy, as long as the target cannot be brought to justice at reasonable cost. One type of cost might be the assassination of Israelis abroad in retaliation, but until such a policy is adopted by the counter-parts in a consistent way, Israel is wise to continue. The CIA is apparently not practicing this approach and has lost the ability to do so competently. It would have been so much cheaper to eliminate Saddam rather than invade Iraq. Likewise, the US under Clinton had a number of opportunities to assassinate Osama bin Laden but Clinton was too timid, which caused untold damage in blood and treasure. The assassins should remember at all time that human life is sacred and should not be shed lightly. But as long as there is no other alternative (by arrest and extradition), let them go ahead.
