Mowing down the Taliban and al-Qaida where they stand is not the irrational goal of a bloodthirsty people.
It is instead a righteous necessity.
President Obama has decided to send as many as 33,000 more troops into Afghanistan to try to do just that.
Fanatics from al-Qaida attacked us, and the Taliban supported the attackers and egged them on.
They have pledged their lives to rid the world of America and Americans. Also the English, the Israelis and anyone else who values freedom.
But these enemies are no longer in control of a government. Allied forces chased the Taliban into the hills, where a substantial remnant remains, still linked with al-Qaida.
They must all be rooted out.
On Sept. 11, 2001, America was rocked by terrorists who seized commercial airplanes and crashed them into the World Trade Center towers in New York, the Pentagon and a field in Pennsylvania. American heroism kept that last plane from reaching probably either the White House or the Capitol.
At first, America and its Allies prevailed in Afghanistan during a period of patriotism not really felt in this country since Pearl Harbor.
It was 68 years ago tomorrow that Japanese planes launched a sneak attack on the American naval base at Pearl Harbor, Hawaii. Our casualties were 2,402 killed and 1,282 wounded.
"Remember Pearl Harbor" became a rallying cry for World War II. The simple numbers 9/11 serve the same role today.
On that date in 2001, terrorists killed 2,976. Nineteen hijackers also died.
While there is some groaning in Congress about the cost of this additional deployment of troops to Afghanistan, no one seriously doubts the money will be authorized. After all, the troops are going. The funds to keep them as safe as we can will of course be forthcoming.
But this is a conflict with many facets.
Chief among them is that the Taliban and al-Qaida are hiding in the wild and uncharted border area between Afghanistan and Pakistan. Because the United States hopes to maintain some kind of relationship with nuclear-armed Pakistan, we venture after the terrorists primarily with unmanned drone aircraft.
And Afghanistan, one of the poorest countries on Earth, has at best a shaky government riddled with corruption.
For there to be an end in sight for American involvement in Afghanistan, that country must do more to clean out the corruption and begin to function as a legitimate government, even if its last election bristled with fraud.
To negotiate this tangled web, Obama will send up to 33,000 more troops to add to the 68,000 already there.
America alone has lost 857 troops in Afghanistan and environs since the invasion in 2001.
That is a terrible price.
Congress must pay to support those already there and the additional troops soon to be on their way, or accept much of the blame for the consequences.
