Russia has yet to up the ante. They have not destroyed Ukraine’s electrical grid, water supplies, bridges, railway system, airports, etc. Ukraine cannot carry out a prolonged war if Russia decides to systematically destroy the country’s infrastructure. And it can do that from inside the sanctuary of Russia’s borders.
The US did something similar to Serbia, including the use of EMP weapons. Agree with the author that a negotiated settlement ASAP is the best solution. A return to the status quo ante bellum is the best that be hoped for.
You bring up a great point, Why haven’t the Russians attacked Infrastructure? That should have been the first to go. Then wait 10-14 days BEFORE invading. Something is odd
