The US-Government doesn’t commit to crucial international laws, not to the rome statute, not to some of the banned weapon treaties. To some of them, they just endorse it, demand others to not violate them, but never signed or ratified themself.
On day1 of the annual UN General Debate, the US President spoke of the South African fight against Apartheit and praised Nelson Mandela, while his Government and Administration is pushing and supporting a much more entrenched and brutal apartheid system. They lie to themself, to their citizens, to their allies and to the World. The also go to wars because of a big lie about WMD Trucks, how could it be fully trusted? Of course it could not.
