the people who live in the last places - the people who are most neglected and least valued by the larger world - often represent the best of who we are and the finest standard of what we are meant to become.

According to UNESCO: there are over 154 million children in the world deprived of education due to poverty, slavery, racism, religious extremism, gender discrimination, and geographical isolation.

I'm no military expert, and these figures might not be exactly right,' I said. 'But as best I can tell, we've launched 114 Tomahawk cruise missiles into Afghanistan so far. Now take the cost of one of those missiles, tipped with a Raytheon guidance system, which I think is about $840,000.

In tribal society, the most important thing to do when civilians are killed in a skirmish is to acknowledge the deaths, and provide compensation. When tribal clans fight, the victor is required to take care of the vanquished widows and orphans, which puts a limitation on bloodshed, and tempers warring groups to try and negotiate a compromise.

The solution to terrorism is education, not bombs.
