Indeed, considering that a submarine would effectively be a Faraday cages deep underwater and hundred or even thousands of miles from the nearest mobile tower, Huawei would need to be using some year 5000 alien voodoo tech for a cellphone to be able to ping a satellite.

Russia enforcing the 'Petro-ruble' for 'unfriendly' countries (or else!) is an economic nuclear bomb. It is successful in stabilizing ruble's currency death spiral in short-medium term, but I question the viability in the long-term, as we see signs of EU diversifying oil imports away from Russia by end of the year. I'm sure gas imports are next, but a longer-term effort.
What the west is asking even demanding of Taiwan is to become yet again another haven for "multiculturalism" western style where anyone and everyone is almost from anywhere and the notion of statehood, patriotism will be seen and interpreted as hypernationalism, jingoistic, a.k.a. hating your own country.

As a consequence the "local inhabitants" will become more alienated from the tyranny of the new oppressive minority since voicing out any signs of displeasure or dissent with respect to the "immigration" cultural wholesale change, language bastardization a.k.a. English will be labeled as "Racist" and intolerant. All of these possibilities are being done without the public being consulted let alone ask to vote for such measures. They are simply imposed by the unelected elites a.k.a. Liberal bourgeois, Liberal intelligentsia of Taiwan.
