After the use of chemical weapons Syrian used in attacks the airstrike that was planned was delayed. There were UN inspectors trying to find evidence that Syria was in fact responsible for the attacks that killed hundreds of people. If they were behind these attacks there would be consequences. While still trying to get all the evidence there is undeniable proof that Syria was behind the chemical attacks.
The US also got it’s information through intercepted phone calls between Syrian commanders. The Obama Administration plans to respond with missile strikes as soon as Thursday to try and keep Syria from killing any more people.
This could end up causing another world war because Russia is on the side of Syria. If war were to break out and Russia joined in, the UK and France could also get involved and with all of the nuclear weapons this could be not only an end of a nation but an end of the world.
