I see it as a threat. albeit of an economic rather than military focus.
Consider the problems of owning real estate....
- It's immobile, so it cannot be removed & taken elsewhere.
- It's subject to local, state, & federal government regulation,
ie, control over what can be done with it.
- It's subject to a lot of taxation. Even if it's unproductive
(ie, unprofitable), there are still real estate taxes.
- If China wages war against us, it can be seized.
Now.....where's China's economic threat?
Obviously, it's not their having property here.
It's that US companies have property in China.
