Last time there were battles on Belgian soil was Napoleon. Germans kind of breezed through twice. Contemporary Belgium however is bordered by two nuclear powers.
Who is the US protecting Belgium with all of this, since the USSR dissolved ?
The action these days is in Poland, Ukraine and the eastern Baltic countries. Even Germany moved a number of armored divisions there.
I hardly see Russia with less than a quarter of the industrial output and half the population walk it all the way to Brussels. I mean... we're not in 1815 anymore...
Moreover, NATO infrastructure and nukes only make it a prime target for ballistic missiles.
I'd be interested in how you get to a positive benefit vs. risk balance in their case. I might have missed some major contrary arguments.
