And again I explained the difference between that as a philosophical idea and a day to day discussion earlier. If you want to take the position you do get, you approve of Netanyahu
How do you reach that conclusion - how are you defining "approve" here? The philosophical idea that our actions are either determined (or random) does not say anything about approval or disapproval in the sense of morality such as thinking an action is "good" or "bad".
People are held accountable for their intentions and actions by our legal system but the legal system acknowledges that these intentions and actions were determined by the person's circumstances/ nature/ nurture. Acknowledging that people's actions are determined by past events does not mean the courts approve those actions or think that those actions are "good".
The act of holding people accountable then becomes part of the nurture/ circumstances that will be a determinant in the future thoughts and conduct of the person being held accountable. Hence, the ICC issuing arrest warrants for Hamas leaders as well as Netanyahu and Yoav Gallant will be a factor or determinant of their future thoughts and actions.
I thought your statement in your post that you thought it was not that "bad" to assassinate extremists (relatively speaking) in comparison to whatever "bad" action the extremist had carried out was an interesting thing to say - as it raised the issue of the problem with vigilante justice that we are seeing in the Israel Palestine issue i.e. each government leader or organisation leader or militant leader deciding for themselves who they consider to be an extremist and deserving of assassination.
Maybe on this forum we all think assassinations are not that bad relatively speaking, but I thought it was interesting - how far is it from one of us living in peaceful Britain thinking/ stating the idea that "it's not that bad (relatively speaking)" to the point where the long-time past or immediate past circumstances/ nature/ nurture of an individual growing up in Palestine or Israel determines their choice to actually order the assassination of leaders and then to the point where bombing innocent people becomes "not that bad (relatively speaking)" in pursuit of political goals.
