They planned riots to surround the WHite House so they could cry, "Halp! HALP! The White House is in danger!" but Trump prevented that from happening by displaying troops (remember the snipers (conspicuously) walking to the white house grounds?
Now the U.N. is meeting on an urgent basis to discuss racial injustice and police brutality in the U.S. and "other regions". Note that London, England is under similar riot attacks.
SO the stage is set, all that is needed is Trump to react in a manner the Deep State and the MSM (but I repeat myself) can spin into a collapse of law and order (portray Trump as operating a police state) to beg the U.N. to intervene.
I believe Nancy Pelosi and others started the strategy long ago, and then made it official in fall of last year via confidential meetings between her "delegation" and the U.N..
What makes you think that the U.N. is more powerful than the U.S.? You think Trump would allow the U.N. to enter in that fashion into the U.S. ( I suppose you mean foreign troops). If they thought they could, they would have a long time ago.
