No one is safer because of this and I wouldn't equate Ukraine/Russia with China/Taiwan, although I agree this will make China's dream of reunification much trickier.
As far they're concerned, Ukraine was given independence by Lenin because he believed in a people's right to self-determination, while Taiwan is "the Alamo" for the losers of a civil war, ones who would later provide a convenient staging ground for the hot wars against communism in Korea and Vietnam.
Yeah I wouldn't get worked up by media from either side for another few weeks, too much misinformation and fog of war. If Georgia was any indicator, they sent newbies to absorb the initial resistance and gain experience, while Spetsnaz and the Chechens will follow on to clean up the insurgency.
Troop and materiel numbers suggest that Russia has allocated slightly greater than the 3:1 ratio that is historically recommended for a decisive victory. That they didn't immediately destroy all of Ukraine's air force has raised a lot of eyebrows, perhaps they screwed up but maybe they are holding back. Baghdad, a logistically tougher objective than Kiev, still took three weeks for the US to conquer and at the time people criticized that it was too fast and intense, and we should all know how that panned out.
The only certainty is that the people of Ukraine and Russia, and definitely not America, will suffer for this massive failure of diplomacy. We'll happily flood the country with munitions while continuing to smother Russia economically, leaving them no recourse but to double down. You'd think when it came time to dismantle the USSR we would've applied a learning or two from the Treaty of Versailles, but alas.
