Kerry hates them because leftists/liberals like Kerry align themselves with Muslims. They’ve been doing it for years now. They want to destroy Israel because that will mean ‘peace’ - but it is the peace of the grave. There is no peace with Islam.
They say Peace ! Peace ! but there is no peace...Are they ashamed of their detestable conduct? No, they have no shame at all; they do not even know how to blush. So they will fall among the fallen; they will be brought down when I punish them,” says the LORD.
Jeremiah 6:14b, 15
Kerry’s daughter is married to an Iranian.
Does that influence his opinions?
