"Mix the Russian/Belarussian/Kazakh spying (Higher than ever, even during the hieght of the cold war) with Chinese spying, and we have a LARGE problem."
Since this spying threatens the pre-eminence of the US military---and hence the survival of American society as we know it---I might even say calling it a "large" problem is an understatement. In ordinary times, it would be called an "immense" problem.
But, consider the fact that the Russians now indirectly control: more than half of our education system K-12, our universities, the Democratic Party, our mainstream media, Hollywood, the bulk of our record industry, the bulk of our publishing industry, and the State Department.
So, perhaps in a relative sense we can downgrade the spying problem to to merely "large".
By the way, though I am familiar with the spike in Russian and Chinese spying on the US (and the UK) I had not heard about the Belarussian/Kazakh component. Any information you would care to provide on that subject would be of interest.
