Yes. Canada and Groenland WILL be invaded. That will trigger a major civil war on US. Canada and Groenland people will be treated like second class citizens and live in poverty. All ressources will be steal by US. In the end, after decades of insurrection, US will be torn apart and broken economically and militarily. That will be the greatest opportunity for China and Russia to take over the west. Other question ?
