What if Singapore goes to war with China? Unthinkable? I can think of three likely senarios. Those who are anti-FTs may wish to vent your views. Pro-FTs can proffer your views too. Differing views will add variety to the arguments.
Scenario 1
Then DPM Lee visited Taiwan in 2004 and met Taiwanese officials. This infuriated China, and said it "harms China's core interests" and it would have "consequences". After some token protests and actions, the Chinese gave face because LKY is his father, and is useful to China because he could explain the Chinese situation convincingly to America and Europe who love to listen to him talk about China.
Scenario 2
Japan patrol boat collided with a Chinese fishing boat in the Senkaku Island. Chinese boat sank, and all crew members perished. China sent warships and submarines to the Islands to confront Jap patrol boats. Singapore reiterated peaceful resolution. China viewed this as tacitly unsupportive of China. China issued warnings that those who did not support her, or condemn Japan, is her enemy. China sent more patrol boats and submarines to the Paracel Islands to lay claim. US 7th fleet aircraft carrier and escorts depart from Changi and headed north. This infuriates the Chinese, who warn of "consequences" for this "unfriendly act".
Scenario 3
China, economically most powerful now, flexes her muscles and becomes more belligerent with its new aircraft carrier. Wants to claim islands in the Paracel and Spratly for marine resources and oil and gas underneath. Send warships and patrol boats and station PLA troops on islands claimed by Malaysia, Philippines, Brunei, Thailand, Vietnam - all ASEAN members. Asean issues strong protest condemning China - Singapore also a signatory. China angry with ASEAN and Singapore in particular.
US Aircraft carrier USS George Washington and escort ships on R&R and refuelling and replenishing supplies in Changi, take off north with much fanfare from western media. China angrier. Concludes that Singapore is in collusion with US imperialist. Expels ambassador from Beijing. Arrest some Singaporean workers in Suzhou and Shanghai for espionage. Chinese PRs and Chinese FTs in Singapore hold protests and demonstrate in many places. Many down tools. Loyal Singaporeans accuse Chinese PRs of ungratefulness, disloyalty and being traitors and throw stones at PRCs living in Geylang area, and Singapore bosses fire Chinese workers on reason of poor business from China. Technically Singapore is at war with China. China wants to make Singapore a whipping boy to taunt USA. Incidentently SM Lee not around anymore to champion for Singapore.
Possible? Probable? Probably? Unlikely? Never know? Anything can happen to small red dot.
