On the numbers... The entire world Wil be mobilized against us. All of Africa. All of S. America. All of China all of India and half of Whites within The US as well as probably 80% in europe/aus. That would be an absolute best-case scenario... Imagine a million Niggers a week arriving at our shores from all directions. Directed armed by the Chinese army as well as the EU army. Imagine huge quantities of middleneasternerns going on jihad... Millions of them backed by oil money. Imagine much of the US military stood down or disabled by sabotage. The fragile internal supply lines for advanced satellites/planes/computer systems smashed/subverted by traitorous Whites allied with them. This is not even getting into national infrastructure destroyed or nuclear weapons used...
This. Is. What. It. Will. Look. Like.
The rest of the world will not be at war during all this. They will have fully functioning cities, power grids, infrastructure, government, water, farms. They will have infinite waves of humanity to throw at us while we fight ourselves. It will only take a year or 2 and it will be over... Unless they want it to last 20 years then it will.
As for space... Maybe maybe not. There are suppressed technologies based on Zero point energy and electrogravitics. Both of them are Extremely powerful. Beyond imagining. They are held in secret. I have some sources and some information I will gladly share. It appears to be the real deal. If it was used it would make it relatively easy to go to space permanently in huge numbers. I'm not kidding. I will post my sauce if you request it. It's a lot of shit and will take you some time to go through. I haven't even see 10% of what I have. There are secrets man. HUGE ones.
