Humanity never seems to learn. During the 20th century, at least 108 million people were killed during all wars combined, and you would think that after so much bloodshed humanity would never want to go down that road again. And in this century, an enormous amount of American blood has already been shed in Afghanistan, Iraq and elsewhere. Unfortunately, the drumbeats of war are starting to get louder once again. Very angry talk often precedes military conflict, and right now there sure is a lot of angry talk going on.

Before we get to the U.S., let's talk about India and Pakistan. They are both nuclear powers, and thanks to a horrific terror bombing last month, they are once again on the verge of war…

Pakistan's prime minister offered to hold talks with India, even as he warned New Delhi to refrain from launching any attacks on his country following last week's suicide bombing in Indian-controlled Kashmir.

Imran Khan said he hoped "better sense" would prevail after the attack on a paramilitary convoy that killed at least 40 Indian troops. But he warned in a televised speech Tuesday that if India attacks, "Pakistan will not merely think of retaliation, but rather, we will retaliate."
