To protect it's citizens from the predatory trade practices of others.

It is irrelevant that the US invented or practices those same trade practices. Doesn't matter. The point is what THEY are doing, and if they are acting in an unfair or predatory the US has to protect itself.

The US can hack Iranian networks with impunity, but let the Chinese try to hack, not the government, but private enterprise it is worth doing battle over.

Should Westinghouse protect itself, the way you and I would have to? Of course not, it's the government's job. Let the taxpayer protect them.

Lousy Chinese hackers!! Spys! Espionage should be illegal everywhere, not just in God-fearing, righteous countries. Like us.

I, for one, will strike back. I will boycott the Chinese army, have no truck with them, won't fight them, will pretend they don't exist. We all need to do our part.
