The is not unlike Obama's victory over Hillary in 2008 and Sanders' leading Hillary now.
I think Corbyn's win is actually great news for Britain: it will marginalize Labour and strengthen UKIP, and thereby improve the chances for brexit.
Brexit is essential in the continental battle to eradicate the EU, and defeating the Left's assault on the Free World.
I believe that Europe and the USA are at a crossroad.
If, in the coming elections - our potus election here, the brexit referendum in Britain, the presidential election in France, and national elections in Sweden, Denmark, Netherlands, and Germany, (where anti-left/anti-immigration parties are thriving or growing) - the people choose pride in their own culture, faith in the free market, and courage in the face of ridicule by the leftist controlled mass media and academy, then the West - the USA and Europe - can be saved.
If Europe chooses the status quo, then - (and this is so very true for Europe because of the domination of the EU apparachiks and the prevalence of parliamentary proportional electoral systems) - it means that in a few decades that Europe shall surely devolve into a leftist/muslim-dominated continent that looks more like AKP dominated Turkey, than even Tory Britain, Socialist France, or Merkel's Germany.
If the USA chooses any democrat to be the next potus, then the entire free world will soon be entirely defenseless and ISIS, Iran, China, Putin and North Korea shall grow more powerful and influential.
The choice is in our hands, as it always has been. Deuteronomy 30:19
I call heaven and earth to record this day against you, that I have set before you life and death, blessing and cursing; therefore choose life, that both thou and thy seed may live.
I ask all people who favor continued mass immigration of muslims into Europe and the West, to look at the muslim dominated nations of the world and decide if they want their nation to become more like them, or not.
That's the key choice we face right now and for the next two years.
I pray most choose wisely and choose life.
