excerpted:
“...Ukrainian President Volodymyr Zelenskiy told the Wall Street Journal in an interview published on Saturday that he was ready to launch the counteroffensive but tempered a forecast of success with a warning that it could take some time and come at a heavy cost....”
The “heavy cost” is zillions of dollars of US money.
Probably not worth the cost in lives of potentially hundreds of thousands Ukrainians. The best move might be is to settle for a cease fire. Continue to build up their defense forces. They need to focus on building the nation of Ukraine.
