I bet israel would defeat india, but it will be devestating for both countries.
First of all, we sell our weapons to india, india uses Israeli developed weapons
Second of all, currently, israel is the only pro-western country in the world with anti-ballistic missile defence system, this system has a 9/10 chance to stop ballistic missiles such as scud c or that korean thing, nukes or not nukes.
Nukes is not an instrument to measure one countries power these days, its just an Intimidating weapon, or a last resort weapon. You dont see the USA using nukes on afghanistan, and you dont see india or pakistan bashing nukes on each other. When you reach the nuke, its can cause a lot of devestation to the entire world, so countries mainly use it for intimidation, ie. if you have nukes, no one would want to go to a total war with you because if a country with nukes is about to lose or to be conquered there is a high chance it will use it.
The only chance I see to see a nuke in the near future is to be used by some crazy muslim terrorist who doesnt care if the entire world blows out as long as israel gets doomed and the united states fall.
So when it comes to actual battle, within too distant countries like india and israel, it comes to technology, deployment, tactics, startegy and experience.
Israel has a newer army, better deployed defence system and airforce than NATO, and the only anti-ballistic missile defence system in the world. We also have the strongest tank and the only anti-tank advanced laser-weapon something ( I dont know much about it cos its secret..) in the world, its supposed to be able to destroy 500 tanks in one day or something.
Israel has proven numerous times that it doesnt matter how small its army is, it can still win (1948, 1967, 1973), I dont think it will be much different with india.
Everyone should thank us anyway, we destroyed Iraqs nuclear base
