Russia is the lost great power
Lost in the endless debate about whether Russia will invade Ukraine is the real reason that Moscow — armed with nuclear weapons and one of the most advanced militaries on the planet — feels so threatened by its neighbors, the NATO alliance, and ultimately the United States. While the expansion of NATO in the 1990s plays a big role, it is Russia’s everlasting internal debate about its place in the world that is the real source of tension. It's a historical black hole no one wants to get sucked into, but unless resolved it has the potential to be a source of armed conflict the likes of which Europe has not witnessed since World War II. Geography and history are both a blessing and a curse for Russia.
