I actually think it would have been damaging to pretend that Biden is perfect. People who can be convinced to vote one way or another aren’t blind to the flaws of the current administration, pretending that everything is rosy will switch them off and they’ll stay home.
Providing honest criticism, where warranted, of both sides and acknowledging the very real concerns around Biden is more likely to keep people engaged and informed. Despite how flawed Biden is, any sane, informed voter chooses him over Trump every time.
Poland is one of the largest militaries in NATO and have a special hatred of Russia. I imagine alongside the UK and France, Russia has nukes aimed at Poland already.
They are plenty threatening already, though obviously adding nukes, even if American controlled, exacerbates things.
