Look, your argument is based on one bonkers article. It is too time consuming to debunk all the nonsense – it is just too much -, so I just try to keep it short. Let me just start with quoting the same
author, since you seem to trust him so much:
Now I don´t know if the first claim is true, but lets take a look at some basic numbers.
The EU spends in total almost 200billion€ (~1,4% of the GDP) on military. They have 1,4million people in the military and about 400.000 are effective deployable fighting force. Russia spends about 66billion€ on its military (in comparison: the UK alone spends 48billion). They have manpower of about 800.000 people, but it is hard to confirm how many are actually ready to fight. The EU has more planes, ships and submarines. Russia´s military is still in the process of modernization and only about ~50% of their forces have modern equipment yet (this will change in the next 5years). They have a serious problem to find enough people that they can conscript and their economy is already at its limit.
So you tell me that an army with a budget 3x higher and better eqipment can´t win a defensive war against Russia?
The only reasonable claim of this article is, that Russia could blitz the Baltics before Nato could react. That said they can do that with or without the USA helping out. I genuinely don´t know if Nato would be willing to go to war over such action, but Russia would collapse if they get involved in an open war with Europe. Their economy would never be able to handle it and their military isn´t structured to fight an open war with europe.
So yes,
your argument is completely bonkers, but it is hard to argue with Americans when it comes to the military. I hope you do a better job when you teach history.
