A week ago, the Independent, once a newspaper based in London, now a website based in London, said the Ukrainians were winning. Today it says they are badly outgunned and near total collapse. But the New York Times still say that, while the Ukrainians had a minor setback, if the US rush those advanced US weapons, the Ukrainians will destroy the rest of the Russian military, which is outdated and flawed, so most of them have already been destroyed by those advanced US weapons, but the Ukrainians ran out, hence the minor setback until more U$ weapons arrive.
Only right wing Fascists that fill up spaces like 4chan use terms like “copium”.
