1 waging war, when necessary, gives israel much control over the conduct of the war. strategies,tactics, use of arms, use of terrain, etc...are all under israel's control. of course, there might be unforeseen occurrances which undermine some of that control. hence, the crucial importance of intelligence and savy change in tactics should such situations arise. 2 on the other hand, israel has very little control over her ability to protect her officers from foreign legal action.israel has tried to push governments, in particular in the uk, to change its ill written and overbroad law of universal jurisdiction. israel will not succeed since the entire purpose of the harrassment is aimed solely at israel. nor will trials in israel against genuine violators of the laws of war succeed. those on the other end do not want just some lowly man of arms. they want the entire army staff and their political leaders. so, for the time being, those who have ever participated in any recent war must choose carefully their travel plans. the high ranking officers must be given diplomatic passports for a certain time.
