US Wants To Deploy Controversial Missile System to Japan

This is probably relevant:

Japan says China airspace incursion ‘serious violation of our sovereignty’

Japan wouldn't be interested in an increased US military presence if they weren't feeling threatened by their aggressive neighbor.

See the map at the bottom of this article: https://www.newsweek.com/china-responds-japan-airspace-violation-danjo-islands-1944781
The plane circled over an area near the islands, then dipped a toe into Japanese airspace. China says it was unintentional.
Responding with an escalation of missile deployments is not exactly proportional. Escalation in general is a very risky thing and doing so casually is reckless and can get people killed.
- China is full of shit about it being unintentional, they've been playing grey zone games for quite a few years now and the nations around them have caught on. I'd argue missile deployment is exactly proportional to an unplanned breach of airspace by a military asset. It's historically a pretty good idea to build up your defense when a neighbor is brandishing their military on your borders
They don't have to pay for it and in a rapidly aging country with a very low birth rate they may not have enough people of military age to put together an army at this point.

Sorry but based on the Nippon Steel controversy we cannot trust Japan with a steel company so therefore we cannot trust them with advanced missile tech.

Its really easy, stop poaching your neighbors territorial waters & threatening Tawain with invasion and you wouldnt need to care about this at all.

How foolish. Japan violently occupied Korea. After the USA nuked Japanese civilians, they took over Japan's dominance of Korea, threatening both Russian and China. The USA was internally debating nuking Korea and also invading China.
When the Vietnamese revolted against French colonial rule, the French brutally repressed them, but still lost. The USA came in to maintain that colonial dominance and destroyed Vietnam, Laos, and Cambodia, all in positions to threaten China.
The Dalai Lama's brother has written a book expressing his regrets around working with the CIA as they used the Dalai Lama and his family to threaten China. The USA was training Tibetan terrorists and literally airlifting them into Tibet to create violence and chaos and undermine China.
When China underwent a civil war and the losers fled to Taiwan and established a brutal fascist dictatorship and executed the White Terror, the USA and UK blockaded the island to prevent the civil war from continuing because the West wanted the fascists to win.
It's real simple, the USA needs to get the fuck out of Asia entirely, they need to stop withdrawing from nuclear treaties, they need to stop occupying Korea, they need to stop training terrorists in East Asia, they need to remove their 600 international military bases, they need to get rid of their immunity for their soldiers from any and all crimes they commit on foreign soil, they need to drop their policy of invading The Hague if a USA official or soldier is ever tried by the ICC, they need to stop trying to undermine MAD and developing nuclear first strike capabilities, and they need to stop brutal sieges of nations all over the world causing shortages of food and medicine.
- Yeah but have you considered that they endanger our hegemony therefore they're bad?
- The Dalai Lama's brother has written a book expressing his regrets around working with the CIA as they used the Dalai Lama and his family to threaten China
  Do you know the name of the book?
Gee, nothing to see here, just some normal US troops less than 2 miles from mainland China
- The National Defense Authorization Act (NDAA) in 2023 paved the way for their arrival to conduct training programs for troops on Taiwan's front line.
  100% legal.
Taiwan, the island occupied by Japan during the war then the nationalists ran off to it and declared themselves independent because Mao didn't have a navy? Imagine if the republicans ran off to Hawaii and declared independence then China formed a military alliance with them.
