we're homeschooling and covered history of classical Greece a few weeks ago. The Peloponnesian War between Athens and Sparta started from very similar circumstances. Athens was spreading democracy and created a large alliance of other states. Sparta was pissed about the alliance because it threatened their sovereignty and political system (military junta). the war raged for 27 years and devastated Greece.
if you watch Putin's speech yesterday, he's pissed about the same thing. NATO expanding to his doorstep. plus some harsh words about the West and threatening nuclear destruction.
unless he backs down. it will be a world war.
