Is this the same John Kerry?

 From Facebook:

George Galloway MP -Is the John Kerry talking of "cowardly crimes" in Syria the same John Kerry who participated in the massacre of millions of people in Vietnam, Laos and Cambodia? Many of them slaughtered by, er, chemical weapons, dropped in a toxic torrent upon Vietnamese civilians by the US airforce? 

Rami Elamine - Yes but this is also the John Kerry who as Senator and on and off chair of the foreign relations committee and previous presidential candidate supported both Iraq wars and the war on terror which has killed hundreds of thousands, left entire countries destroyed and worse off, and led to the growth of Al Qaeda and jihadists (and who will be the main beneficiaries of the US's bombs in Syria).
