Allow them to engage in the international market like every other country, don't create a crisis by cutting them off from the financial system to enforce regime change
What the USA need is a war on its soil, where missiles and grenades go off every minute only then shall they appreciate the value of dialogue
That country started off with noble pursuit but a lot of the problems in the World today has the USA fingerprint all over it, Venezuela is to rich for them to ignore now, and I say its gone to far into the process for them to turn around now. It embarrassing after a month, the objectives they set haven't been achieved.
The USA would lose a lot of allies in the coming months, most countries especially in the Western hemisphere especially Latin America and Caribbean are just playing around, accept whatever they give and vote against them in whatever they put forward, as soon as a stable financial fiat system emerges outside the control of the USA, the USA would find itself in a hole.
Give it some time, right now its a matter of time, they feel they are to big to fail and their sense of superiority would stand forever, its going to be sad but from the ashes we would rise a better world where people respect each other difference
