"Годі скиглити - беріть лопати і почніть хоча б окопи рити на своїх східних кордонах..."

Американці з норвежцями майже цим вже займаються:
U.S. stationing tanks and artillery in classified Norwegian caves.
Marines are prepositioning battle tanks, artillery and logistics equipment inside Norwegian caves as the U.S. pushes to station equipment near the NATO-Russia frontier.
"Any gear that is forward-deployed both reduces cost and speeds up our ability to support operations in crisis, so we're able to fall in on gear that is ready-to-go and respond to whatever that crisis may be," Col. William Bentley, operations officer for the 2nd Marine Expeditionary Brigade, said in a statement Friday on the Norwegian deployment that called the caves classified.
The deployment of new equipment to the Cold War-era caves comes amid renewed tensions between NATO and Russia. Russia shares a 121.6-mile long border with Norway. The border was heavily militarized during the Cold War, and the Russian navy's Northern Fleet is in Murmansk, about 100 miles from the border.
