US Intelligence believes that Malaysian flight 17 was shot down by a SAM (Surface to Air Missile):

Confirmation of Missile strike on Malaysian Flight

This is a horrendous act that has not been seen in European air space for a decade, according to the Gaurdian the last flight to be brought down was also near Ukrainian air space.

I am not blaming either side for this senseless use of military weaponry on a civilian target. If this was intentional, no nation on earth should be allowed to be held unaccounted. Civilian targets are illegal under the Hague Conventions after World War II. The last couple of downed civilian aircraft have been "accidents" according to the involved nations, including the US, Russia, and Ukraine. However, with modern technology and new international standards on Civilian plane transponders, I highly doubt the perpetrator can claim ignorance or accidental firing without a great amount of incredulous fortune.

No matter, who perpetrated this, it's tragedy of human nature. Whether it is the Ukrainian's overzealous need to protect their border or Russia's arrogant push to reclaim its "former glory" or rebel groups seeking to make a "point" to the world community, our human nature was at the heart of the story.

As long as mankind lives, works, and strives, conflict is unavoidable; we can create laws, international groups, and hold protests all day long, can we change human nature? What is the point of it all, if mankind wants to knock off each other in some Darwinian joke that is life (if the meaning of life is in order to be sufficiently intelligent, you must kill your own kind until you destroy your entire species)?

I just find the world to be considerably tragic and it's mostly our own fault, because we don't consider each other in our actions.

Maybe that's just me, a selfish man, who as he grows older is becoming less selfish (Maybe, I'll vote Democrat one day at this rate. )

I am just reflecting and trying to find meaning in a world that doesn't seem to offer any.
