Questions to be answered...

I was lying in my bed wondering.....What do we know for real?I mean,when we sit in front of the TV screen,watching the news,what information we get is real for sure?How can we express our opinion about anything since it can be distorted on purpose to make us think in the wrong way?
For example,a few years ago,a woman appeared on the tv,claiming to be a nurse in the war between Iran and America and with tears in her eyes she admitted that american soldiers were treated really badly and they were even tortured from Iran's goverment.That news filled american people with deep hatred for the other side,whether it was true or not so the war became even worse.Later it was proved tht the so called nurse,was in fact the niece of a member of parliament.So what?The purpose of turning american people against Iran had already been fulfilled.
