Google released the stable version of Chrome, and funneled significant resources into marketing it. This was the first stage of their strategy - they focused on firstly making a good product, and the squeeze on users only came later (and is probably only just starting in the scheme of things).

To quote Du Mu’s commentary on Sun Tzu’s Art of War: “If our force happens to be superior to the enemy’s, weakness may be simulated in order to lure him on; but if inferior, he must be led to believe that we are strong, in order that he may keep off”.

So the fact they are switching from simulating weakness to pleading strength is not necessarily a good sign. That said, they may be hoping that the enemy will see it as a sign of weakness, and launch an attack that they actually are well prepared to win.

Russia already had an agreement with Ukraine to respect the 1994 boundaries of Ukraine - the Budapest Memorandum.

It’s like if someone promised not to burgle your house. Then they burgle your house anyway - but promise they’ll stop burgling for real if you promise to let them keep the stuff they already took, and throw in some more, and promise to never to lock your doors.
