Don, if I make an error of fact (I don't believe I have) you could just identify it and I would apologise and withdraw.
Instead you screech "liar" in large font capitals.
Why?
It indicates an emotional involvement I find curious and distasteful.
Can we not discuss this like grown-ups?

perhaps you are not as certain as you claim
I have never claimed certainty.
I just point out the absence of evidence for your lurid assertions.
I make none myself.

Israel's actions which you have tried to excuse on the basis that other countries behave worse
No.
Not to excuse anything.
I make the comparison to expose the hypocrisy and prejudice of those who single out Israel for attack when it is far from being the worst offender, if an offender at all, while ignoring the crimes of real and serious offenders even in the same region.
Like you and Jim do.
