Yes
Even if I accept your poor statistics about BD military, even then IA has kept on surrounding BD with 300,000 all season during peacetime. By the way, does China need to annihilate a weak IA, which has only 3000 tanks, with the help of Pak and BD? Even a weak BD has more than 650 tanks and 450 amphibious APCs. Pakistan has more than 1,500 tanks.
How do you talk big with a troop that cannot fight even against Jharkhand Maos. You will cease half of your land if Pakistan and BD joins together in a war. You are incapable to mobilize in two fronts. Ask any of your generals. So, better keep on courting BD friendship. It is a survival kid for India.
Firstly, you're pathetic at insults.
Secondly, you need to appreciate the fact that militarily, BD is a weakling, at best. Your first and only line of defence is china. But as I have pointed out earlier, history suggests that for all parties to simultaneously converge on India is little more than a wet dream which helps emasculated / insecure farts in getting off.
But i will, however, concede, that in the unrealistic situation of all 3 countries attacking india, the odds would be stacked against us - There, that should help you get off tonight!!
Thirdly, you mentioned tanks. For one, india has somewhere about 3,500 of them. India also has a license to manufacture another 1000 T-90s. As for BD tanks, it mostly comprises of ageing platforms such as the Type 69II - try scaring a few unarmed monks with them.
Next, the army has not been deployed to tackle the maoists. Indian Army boots are designed to land hard, exclusively, on your rear end.
Fifth, you didn't reply on the mismatch in the defence budget. India is ramping up, militarily, at a rapid pace, which is enabled by a defence budget that is more than 1/3rd of BD's GDP. What do you plan to buy for USD 1.5 billion, to match us??
Finally, you are right. Engaging enemies on two fronts will be challenging, PROVIDED that the two enemies are Pak and China. These two are legitimate powers with ACTUAL capabilities, quite unlike BD.
The bottom-line is, there is no conceivable scenario where BD can ensure the integrity of its sovereignty, WITHOUT external aid. Basically, you guys are desperate for a fu@k, but cant get it up without a heavy dose of viagra.
