Do you think Singapore, Indonesia and Malaysia will allow India to choke off their Straits?
No. On their own they certainly won't. The scenario we are looking at is if they are arm twisted into compliance by external pressure. The Soviet Western Cold War is a good example. Some countries like France didn't really want to antagonize the Soviet Union and even the then (West) Germany did not like nuclear weapons on its soil, and an apparatus for choking off the Soviet Union but that is what happened.
Global Imperialism needs proxies that can fulfill a role that brings dominance without risking a full fledged war. A good example is Israel, which dominates the Middle East and North Africa.
As part of the plan India has emerged as the "Israel" of South and South East Asia. The prime role is to contain choke and ultimately defeat China. Earlier Japan and South Korea had been chosen for this role but they are unwilling partners preferring the welfare of their population to hyper-nationalism and war. India's military capabilities are being enhanced ten fold. It has been gambled that India's burgeoning young population will make great military manpower. India's current hyper-nationalist, religious extremist environment has a popular sentiment that makes a war fighting scenario ( and the losses it entails) very acceptable. With poverty reduction and prosperity the populations of economically strong nations have little taste for war. No one wants to die for an abstract "cause" which is why Japan, South Korea, Singapore, Malaysia, Philippines all have very reluctant support for any war, These nations have seen horrible conflicts in their times and suffered occupation and mass destruction.
India is a notable exception. There has been NO mass suffering because of war in India since the late 1700s. All conflicts in modern post-independence India have been brief, on the borders and the Indian population believes they have won all those conflicts ( yes, even the 1962 India China war). The population of India fed by its own media hype and political outfits are rearing to pitch headlong into a war, preferably with Pakistan first and then China. It is openly argued over the Indian media that to fight with China, first Pakistan must be destroyed, occupied and its population either expelled or converted to Hindu sub-caste.
This suits the Western powers as long as India takes on China after defeating Pakistan. A propaganda currently popular on Social Media states that the Pakistani nuclear and missile threat is a giant hoax. So Pakistan can be defeated and occupied. It is such delusions ( unfortunately even within the upper echelons of the military ) that errors happen and nations stumble into war.
