Our response to France.

I will preface this with France is our ally by history and treaty, so we will support France.
I am listening and reading the reaction of people who want to bomb them to the stone age, send troops, burn the oil fields and nuke them. I'm trying to figure out what the fuck they're talking about.
This approach seems to ignore that these countries are sovereign nations and without them inviting us in we would have to declare war on their governments. I keep hearing about re invading Iraq, do these lunatics understand we would have to declare war in order to do that? So we would have to fight Isis and the Iraq military. Same with Syria. We would have to declare war on Syria. Iran and Russia would be thrilled.
Another thing this has morphed into this happened to us. No it happened in France. And it's Obama's fault. He is not the president of France. Yet he is weak and to blame. This is deranged.
Let's put this into some kind of perspective. At least 8 terrorists attacked 6 venues in a large city. This wasn't an attack by a foreign government. There is no country to bomb. I suspect either these terrorists were home grown or recently returned from fighting in the mid east. They may be french citizens. Should we invade France ?
The other thing I hear from the right is screaming about our borders, yet the people who attacked us did not sneak across our borders and the lone wolf attacks that occured here were from American citizens or people entering legally. Obama has kept us safe. France could have all intel in the world but because the EU has free travel between EU countries it would be hard for them to know who is in France. The EU essentially dissolved its borders for economic reasons. That is not what is happening here. Trying to conflate our borders issues with an eu country is ludicrous.
So far Obama hasn't done anything stupid and I am very thankful he is our president, not McCain or mitt.
It is this sort of thing that convinces me I will vote for whoever the dem nominee is, even if not my 1st choice because Trump, Cruz or Carson.
