Again, there is no 'us'.
Is America allied with your country? If so, then our countries have common goals and ambitions. As an ally, our countries meet secretly and scheme.
America is not the centre of the world.
Yes it is. America is the only existing superpower. Here, I'll put it in perspective for you:
There are 192 countries on earth. The United States of America has bases in 130 of them.
How many countries does your homeland have military bases in?
The Japanese government gave original estimates. Of course the estimates vary, as more people are discovered alive or dead (or more people actually die...radiation sickness is mercilessly slow sometimes). Nuclear technology exists in many countries, as any intelligent person (know any?) will be able to tell you.
When a country claims to have Nuclear Technology it's a scare tactic, nothing more. Whether or not it actually does is debatable. Claiming to have Nuclear weapons is something which instantly increases a country's status in global politics. With a threat of a fiery annihilation looming down your enemy's throat, victory is assured. That's exactly what we are told North Korea is doing after all.
You must think your mistrust of government makes you smart, but in fact taking any position that is one way or the other is foolish.
There's nothing smart about blindly believing the word of a massive powerful entity with inconceivable motives. A government is an entity which controls the flow of money, the education of its people, the outlets of the media, and wages war with whomever it sees fit. The Government can and does murder at will in order to satisfy its desires.
Distrust is key to all global politics. Never trust a government.
