Putin warned that the US defense missile shield could cause us to feel too safe, thereby causing the US to be more aggressive in dealings with the rest of the world. He believes a "balance of power" is key to security.
Apparently Putin has never met a Tongan, or has never had the experience of being the tallest or biggest person in a social circle. I can also speak from experience, being tall among my peers, that feeling big or safe does not make you more aggressive. In fact, most large people are giant teddy bears, guarding and not abusing their power. Probably if they were aggressive, society would see them as a threat and would not tolerate them.
Only someone with Putin’s insecurities could feel this way. What does he think, that every country should have equal weapons and power, then there would be peace on Earth? This is just the type of leader who abuses power if he were to come into it. But if the US is as well-guided as I know we can be, we would not be foolish enough to flaunt our power in the world. Clearly our leadership has betrayed this optimism at times, but I believe it is who we intend to be as a whole. The focus should be on similarities and diplomacy, not on whose missile can penetrate deeper.
