@msolga,
I offer my opinions without too much reservation, and welcome people to challenge what I say.
The secretary of defense and the secretary of state would have provided input to Obama to get their views.
I have always said that there is a conflict of interest to get input from soldiers/generals, because wars is their game and livelihood. Without wars, they can't command troops, or make a name for themselves. Most promotions comes from wars, not peace.
That being said, us armchair critics are probably working with only part of the most important information available to the president and his staff.
When congress was preparing to vote on the Iraq war, I wrote to Senator Diane Feinstein and told her not to approve the war. She wrote back and said that the information that the intelligence they have requires congress to approve the war.
Six years after the war, us armchair critics were right, and congress was wrong.
We can only come to our conclusions through the exposure we get from reading and listening to the media. However, we are now completing over six years in Iraq that was supposed to cost only $50-billion, and towards the end of last year, it was costing our country some $2-billion every week - all while our economy tanked and the federal deficit grows at untenable levels. 9-11 cost some 3,000 lives, but we've already sacrificed over 4,000 of our military, and untold tens of thousands of innocent Iraq lives as well as destroying their infrastructure.
Our economy is barely staying on life support, and Obama makes the decision to send 30,000 more troops into a war zone; how many more must our military sacrifice and how much more of our treasure must we spend for a war that's in a country with a corrupt government and control of the country falls into many different groups including the Taliban and al Qaida? If they are a threat to the US, they must also be more of a threat to Europe and their surrounding countries. Why are we footing most of the cost of this war?
We are not the world's police; it's logistically an impossible goal. We represent only five (5) percent of the world's population.
