How should the United States respond to the terrorist attack in Paris?

France has been too lenient with Muslim immigration, also allowing the "no enter" zones. This is happening in several other countries. Muslim terror groups are given free space to organize. Without limiting these zones, Charlie will happen again.

first, close our borders to prevent any illegals from entering.
second, do not let any Muslims into the country, legal or not.
third, allow authorities to monitor every mosque in the USA. If they refuse to be monitored, shut them down.
fourth, do not allow any laws to be applied in the USA except USA and state and local laws, not Sharia. Enough madness.

Support France exactly like they did us after 9/11 and the attacks on our citizens! An aside, we'll never stop illegal immigration until we quit our welfare system as "Big Business" wants their spending power. Let them clear the down fallen wood in all our forests for their pay!

Offer France immediate support with security and intelligence and provide it if requested.

Yes, we have to give full support to France, we also need to increase our surveilance within our borders. I also feel that congress should override the President on Islamic Terrorism and pursue the enemy until they are caught. There is a small price to pay for security, better spent than buying votes like the liberals do. It would help to capture these terrorists so we could talk to them and interrogate them.

The lack of intelligent leadership from our administration regarding terrorism leaves little to offer France that they don't already have themselves.

Look, we must acknowledge that Islam is a cult of terror. It will not go away. It must be dealt with the same way the Romans dealt with this type of ideology or philosophy.

I can almost guarantee that France and the U.S. are sharing intelligence.

Having said that, finding the critical data in the morass of intelligence is difficult. It is made worse by a President and Administration who lack the moral courage to identify the enemy, the strategic sense to have proper and reasonable rules of engagement to protect our forces on the cutting edge, and the honesty to call terrorism terrorism and not the insane classification of Fort Hood as "workplace violence."

Ladies and Gentlemen, the people who run our country today, who control the media, and who direct our assets against terrorism are more worried about conservatives and former members of the military than they are about those who have vowed to destroy us and our systems of law and society.

P.S. Islam has never been a "religion of peace," unless you mean taking a piece of this and of that by means of force. Read a little history and see what it took to stop the tide of Islam in Iberia (Charles Martel and the Battle of Poitiers in 732), the Mediterranean (Battle of Lepanto in 1571), and outside the gates of Vienna in 1683. They don't teach anything about history in our schools today, but for hundreds of years Western Europe battled against the expansion of Islam.

This is not a recent problem. This has been going on since the 670s with only a few relatively short breathers. Folks, Islam since it's founding has been a religion spread predominantly by violence and force and to a relatively minor extent by voluntary conversions i.e. the U.S. prison system.

Also remember that shortly after we first became a country under our Constitution that our first foreign war was not again Mormoms going door-to-door but North African Islam. Maybe history doesn't repeat itself, but as some wag stated, "It rhymes." To misquote George Santayana, "Ignore history at your own peril."

Investigate all mosques /Muslim's in this country, any hits deport them immediately.
Unfortunately with this administration being SOCIALIST/COMMUNIST, it will not happen.
Unfortunately, this will probably happen to this country soon enough.

The idea that this would happen in the United States is unlikely, at least in the context of doing this to civilians. I believe this is because they do not fear the police or government or military, but fear the individual American that MAY be concealed carrying. France was a soft target--full ban on firearms, a liberalized people that have allowed police "no-go" zones that are for only Muslims, including the implementation of Sharia law in these areas, all culminating with what we have seen the past week.

Now, before anyone throws the Ft. Hood massacre in, that was committed by a sole man that invoked what we believe to be radical Islamic views on fellow servicemembers. It was terrorism, but against primarily military personnel on an installation.

Is there any help for a Nation that puts their Police out unarmed? The entire country seems to be a soft target. The Swiss model of having Veterans keeping their weapons should be adopted here as well.

It is time for all countries targeted by Islamic terrorist groups to share information. It seems that none of them trust each other with that data, and the terrorists count on that mistrust to continue their terrorism. The intelligence organizations of each country desperately need to work together, even if it means not keeping the great leaders informed.
