"generally decry"? I am curious. We are talking about a country which calls itself a democracy, yes? If there is a majority that has a problem with what the government does, it is not clear to me why said majority doesn't take the matter into their own hands and vote a government that, you know does not indulge in "heavy handed action".
Of course, if we are talking about anecdotal evidence that the people around you are opposed to crimes against the Palestinian people, carry on.
Heavy handed action does lose you elections in Israel, which is by many measures more of a democracy than the US or the UK. There is no two-party gridlock. Parties appear and disappear. Compromises are made, settlements have been given up.
However they need to draw a line when their very existence is not respected.
I honestly don't think anyone could realistically do any better than they are doing, in their position. Lots of people would not accept anything other than Israeli self-destruction.
Of course, if we are talking about anecdotal evidence that the people around you are opposed to crimes against the Palestinian people, carry on.
