I do consider it another bluff: of course, it must be taken seriously, too.

I do consider it another bluff: of course, it must be taken seriously, too. But, foremost, it's - still - a bluff (otherwise, nukes would already be flying).

....no idea what should Ukraine do, except for keep on pushing.

The West has already missed a golden opportunity: had it delivered enough heavy artillery and air defence systems during the summer, Ukrainians could've liberated Kherson, Zaporizhzhya and halfof Luhanks - all before Putin came to the idea for this 'mobilisation, light'....

Now the sole solution is: ship yet more weapons.
