I wouldn't state in any sense that we are vulnerable nor overreached as some would choose to believe. If Russia wants to continue to sell weaponry to crazy muslim extremeist such as Iran and Syria then so be. The quality of the missles sold to India so far pretty much speaks for itself. They failed and the quality was at the least poor. The mismanagement of funding for India's carrier also speaks of military/political disillusion. Russia is doing nothing more then a poker face and trust me she is very worried about the missle shield and the countries that want them both politically and defensively. They are also very concerned that India will decide to shop elseware taking the carrier funding with them. If that happens Russia will be in quite a dilema so to speak.
