First off, he only mentions weapons sales as crimes for ONE president- Jimmy Carter, for all the rest he spells out the specific orders of aggression and violence that they carried out.
As for the bizarre comparison, no, that's not how it works under international law. A state selling weapons to one that is knowingly committing atrocities is illegal:
As noted in an
earlier article for
CounterPunch, arms transfers to Israel—even before the ICJ interim ruling—violate customary international law, including the International Law Commission’s
Draft Articles on Responsibility of States for Internationally Wrongful Acts, as well as international humanitarian law, including
Common Article 1 to the four
Geneva Conventions of 1949. For states that are members, arms transfers to Israel also violate the
Arms Trade Treaty, the
European Union’s Common Position on Arms Exports, and the Organisation for Security and Cooperation in Europe (OSCE)’s
Principles Governing Conventional Arms Transfers.
Carter's only defense would be that he wasn't aware that Indonesia was committing atrocities.
