IMO. The situation will be like this.
1. Russia - Will start mobilizing and exert pressure on Chinese Border but not declare war
2. USA will sit idle and watch. They will supply older weapons at lower rates, but otherwise only pay lip service to India. Their military assistance to Pakistan will also stop.
3. Afghanistan will seal its borders(ok at least it will try to) and bark against Pakistani aggression
4. Nepal and Bhutan will try to stay neutral. But China will have to either bring them in camp or overrun them. So later they may be forced to join the Indian camp.
5. Bangladesh will stay neutral as far as possible. They are likely to join later - they will be opportunistic. Will join China overtly if they are winning, covertly India if she is.
6. Myanmar will covertly support China.
7. SE Asia will remain neutral.
8. Saudi Arabia will cut of oil supply to India if she is doing well saying that supply line is not safe.
9. Iran will supply oil to India covertly.Also with intel and other support.
10. Central Asian Republics will follow the foreign policy of Russia - unlikely to support China or Pakistan
11. Europe will debate and pass lots of resolutions but do nothing.
12. Latin America will continue as if nothing happened.
13. Israel will send a 'volunteer advisory group' to India and mobilize herself.
14. Africa will stay out. In fact they would supply China overtly.
15. Australia will support India - though not declaring war against China/Pakistan.
16. Japan would cut of diplomatic ties with China and monitor war. They will mobilize. Same for South Korea.
17. Middle Eastern countries by and large will lend a lot of money and oil to Pakistan but for real support in manpower - they will do nothing.
18. Sri Lanka will covertly join China/Pakistan and allow Chinese Navy to dominate the 'Indian Ocean'.
This thread is hypothetical.
The question i am interested in is that || 'Which regional state/states in your opinion will join India in an 'active combat' scenario if India finds itself in a FULL SCALE 2 front war against China and Pakistan' ?
I am not talking about diplomatic/economic support, but the state/states that might fight alongside India in this scenario.
The multiple choice option is available.
Best Regards.
