The human tragedy unfolding in Pakistan right now demands our full attention.

Flooding there has already stranded 20 million people, more than 10 percent of the population. A fifth of the nation is underwater. More than 3.5 million children are in imminent danger of contracting cholera and acute diarrhea; millions more are in danger of starving if they don’t get help soon. More than 1,500 have already been killed by the floods.

This is a human disaster.

It’s also a frightening opening for the Taliban.

Yet so far only a trickle of aid has gotten through. As of today (Thursday), the U.S. has pledged $150 million, along with 12 helicopters to take food and material to the victims. (Other rich nations have offered even less – the U.K., $48.5 million; Japan, $10 million, and France, a measly $1 million. Today (Thursday), Hillary Clinton is speaking at the UN, seeking more.)

This is bizarre and shameful. We’re spending over $100 billion this year on military maneuvers to defeat the Taliban in Pakistan and neighboring Afghanistan. Over 200 helicopters are deployed in that effort. And we’re spending $2 billion in military aid to Pakistan.

More must be done for flood victims, immediately.

Beyond helping to prevent mass disease and starvation we’ll also need to help Pakistan rebuild. Half of the nation’s people depend on agriculture for their livelihood, and a large portion of the nation’s crops and agricultural land have been destroyed. Roads, bridges, railways, and irrigation systems have been wiped out.

Last year, Congress agreed to a $7.5 billion civilian aid package to Pakistan to build roads, bridges, and schools. That should be quadrupled.

While they’re at it, Congress should remove all tariffs on textiles and clothing from Pakistan. Textiles and clothing are half Pakistan’s exports. More than half of all Pakistanis are employed growing cotton, weaving it into cloth, or cutting and sewing it into clothing. In the months and years ahead, Pakistan will have to rely ever more on these exports.

Yet we impose a 17 percent tariff on textiles and clothing from Pakistan. If we removed it, Pakistan’s exports would surge $5 billion annually. That would boost the wages of millions there.

That tariff also artificially raises the price of the clothing and textiles you and I buy. How many American jobs do we protect by this absurdity? Almost none. Instead, we’ve been importing more textiles and clothing from China and other East Asian nations. China subsidizes its exports with an artificially-low currency.

If you’re not moved by the scale of the disaster and its aftermath, consider that our future security is inextricably bound up with the future for Pakistan. Of 175 million Pakistanis, some 100 million are under age 25. In the years ahead they’ll either opt for gainful employment or, in its absence, may choose Islamic extremism.

We are already in a war for their hearts and minds, as well as those of young people throughout the Muslim world.

Right now, Islamic insurgents are using the chaos as an opportunity, attacking police posts in Pakistan’s northwest while police have been occupied in rescue and relief work. Meanwhile, lacking help and losing hope, many Pakistanis are becoming increasingly hostile toward President Asif Ali Zardari.

And, of course, Pakistan has the bomb.

What can you do? Government efforts are important but so is private giving. Check the New York Times’s Lede blog for organizations providing disaster relief. The Oxfam website has lots of good information about who’s doing what, and how effectively.
