BILL GERTZ: Russia Sharply Expanding Nuclear Arsenal, Upgrading Underground Facilities.

Russia is aggressively building up its nuclear forces and is expected to deploy a total force of 8,000 warheads by 2026 along with modernizing deep underground bunkers, according to Pentagon officials.

The 8,000 warheads will include both large strategic warheads and thousands of new low-yield and very low-yield warheads to circumvent arms treaty limits and support Moscow’s new doctrine of using nuclear arms early in any conflict.

In addition to expanding its warheads, Russia also is fortifying underground facilities for command and control during a nuclear conflict.

That’s disconcerting.
