If Russia can’t beat Ukraine one on one, add in European troops and equipment It will only get more difficult for Russia. They can threaten Europe with nukes, but France and England also have nukes.
Russia has been fighting NATO for the last 3 years - not merely "Ukraine."
It's been NATO armor, vehicles, intelligence, missiles, ammunition, spec ops, training/tactics, and money on the battlefields of Donbas. The notion Russia is struggling to fight sad "Ukraine" is more propaganda designed to turn zeepers brains to mush.
Russia has merely been planning and waiting for the entry of "troops."
If Europe wants to finalize its suicide, started in 1914, in the form of a 3rd continental war, Russia is ready for them.
Russia has more men, money, resources than the Ukraine by far. In addition, they have the greatest nuclear arsenal on earth.
Brit and EU troops in Ukraine would be are less than worthless - IMHO. Absent U.S. putting boots on the ground in Ukraine OR .... Britain and/or France an/or U.S. using tactical nukes in Ukraine ....Russian will take Ukraine through attrition.
Am I missing something?
