syria....why should we get involved

 i have seen a lot of bull on the internet saying we should not get involved in Syria.well,think.if we do not stand against this then what is the use of any western power having a military?the world should be outraged when a leader of a country launches a poison gas attack against his own people.we should immediately demand he step down and be tried as a war criminal.this should not be allowed by the west or the east.anyone who allows it is barbaric.this man did this,killing thousands.and now one million children are refugees.and this war will spread even if we do nothing.because that is what Syria leaders want.we allowed Rwanda.and i am still ashamed we did nothing.we should not even consider standing by and allowing this to go UN answered.and i if i could would ask Russia to put pressure on Syria to stop and its leaders to leave.
