Australia. india may have nuclear weapons but nuclear weapons are hated by the UN and any other nation that doesnt have 45% of there population as poverty (and i would like to point out that there is a UN nuclear treaty that was signed by every country in the world other than INDIA! and North Korea, and i stand to believe that north Korea is lead by a dictator so this says a lot about india)so if india were to use nuclear weapons the country would exports, imports and stock exchange with Australia, china , USA and Europe. we also have have really BIG allies like the U.S and England. our technology is more up to date. they maybe bigger but we have a better quality ARMY, NAVY and AIR FORCE. we have really good invasion proof seas with constant patrol from the NAVY and airfoce. the airforce also has the AP-3C orion which whic has radar that can scan for miles for submarines and warships, it has anit-submarine and anti-ship weapons that can destroy them in one shot and acts as a early warning system for invasion.
america
India win tha macha
no china has much more men
India and Nepal currently have very good relations and a war between them is highly unlikely. That being said, India would win a war with Nepal quite easily since its military is much larger and much better equipped.
INDIA
sure,
The USA would massacre the Indian military in under half a second
Australia Failed..... Hard
Yes
india only win
No one would win especially if either of them uses nuclear weapons. The whole world will lose.
The United States, though both have nuclear weapons.
