If we're not careful, the Chinese and the Russians someday will sink one or more of our aircraft carriers:
The US Navy is facing better and more numerous Russian submarines capable of taking out aircraft carrier groups. The service can’t ensure full awareness of Russian sub activity, CNN reported, citing [an] American admiral.
"The submarines that we're seeing are much more stealthy," Adm. Mark Ferguson, commander of US Naval Forces in Europe, told the news channel. "We're seeing [the Russians] have more advanced weapons systems, missile systems that can attack land at long ranges, and we also see their operating proficiency is getting better as they range farther from home waters."
Russian deployments of attack and ballistic missile submarines are currently at levels unseen since the Cold War, he said. The US has 53 submarines in service and the number will drop to 41 by the late 2020s due to budget constraints, Ferguson added.
Even with the current numbers, the Pentagon can’t monitor all Russian subs, according to retired Adm. James Stavridis, a former NATO supreme allied commander.
"We cannot maintain 100 percent awareness of Russian sub activity today," he said. "Our attack subs are better, but not by much. Russian subs pose an existential threat to US carrier groups."

One of the reasons Russian subs are "much more stealthy" is that Japanese computer controlled equipment for the machining of quiet propellers was sold illegally to the Soviets/Russians, and the first deal of its kind allegedly was brokered by former US Defense Secretary Frank Carlucci.

Treason doth never prosper: what's the reason?
Why, if it prosper, none dare call it treason.
In today's world the traditional concept of treason no longer has any meaning to the powers that be. Their loyalty is only to themselves and to their loot, and they have found multiple ways to prosper from selling us out.
