President Trump has already stated that he does not want war and that if SA wants our help they will have to pay for it.
Which leaves a back door open to Russian offering their latest air defences (for a price of course).
SA has to worry about the rest of their oil production before testing Iran's plan to wipe them out and hear all of Europe yell "Leave Iran's oil productions alone they are all we have left to get through winter"
Which is not true with Russia standing by to ramp up oil production.
Oh what a tangled web we weave
