Well your post implied that deals were bad, but not as bad as handshakes.
It did? It certainly was not intended. As I said, the deals are irrelevent to the morallity of shaking a murderers hand in my mind.
International criminal makes no difference. He still had power. We still needed to negotiate and deal with. Hence you give a handshake. It's no buggy and just how business and politics works.
You see I think it does, we have a moral obligation that should be interwoven into everything the state does particularly in relation to those facing accusions of crimes against humanity.
We did not have to negotiate or deal with him. They chose too. If anything we had a responsibility to not prop his tyrannical rule. The West may undertake business with states and criminals in a hypocritical manner, it does not make it correct or moral for doing so in the first place.
"It's just business". I can't argue against that, but it's still wrong in terms of moral application I firmly believe.
