The Vietnamese proved that it's not the bombs you can throw at the country - it's whether you have hearts and minds on your side.

The Americans learnt from that and went to Iraq claiming to have hearts and minds on their side - but quickly discovered that, in fact, they did not (and still do not).

The Americans need to take stock of their own actions in this conflict - they put Trump in the white house, they allowed him to be influenced by other governments, they gave him the power to get involved in the conflict.
