YES, of course it is. How would you feel about Chinese military bases in Amarillo, in the free-and-sovereign nation of Texas? Anti-aircraft systems? state-of-the-art fighter jets? But Xi Jinping said they are all purely defensive!
Or, on the other hand, is it, like all NATO arrangements, a defensive intervention meant to halt the hegemonic intentions of Russia?
Nonsense. Non-offensive? Just ask Serbia, Syria, or Libya about NATO. Ask Germany what happens to your independent gas-line connections if you step out of line.
100% love it.
