An unmanned drone strike took out 4 suspected militants in Northwest Pakistan today.

This newest strike comes one day after a U.S.Senate Subcommittee voted to cut aid to Pakistan by 58%. The Subcommittee vowed to cut even more if supply lines to Afghanistan are not re-opened. The panel said that they do not want to invest capital in an uncooperative nation.

This cut made by committee is far from complete. The plan would still need to go before the full Senate for a vote as well as the House and then still clear the President’s desk before it would be implemented.

Pakistan has called for an end to drone strikes within their borders, but the U.S. countered by saying that the strikes are necessary in the war against Al Qaida and the Taliban.

Pakistan cut off U.S. supply lines to Afghanistan after the attack that killed 24 of their service members. Pakistan has called on the United States to apologise for that attack. The U.S. has ignored those calls, and only issued condolences for the soldier’s deaths.

The U.S. has already cut $3 billion of military aid to that country after the supply lines were shut down. The United States now uses alternate supply routes through Russia and Central Asia via land,sea and air. Those routes are more expensive.

President Obama refused to meet with Pakistan’s president, Asif Ali Zardari privately during the NATO gathering that took place in Chicago this last week. Pakistan was invited to the summit because of signs that Pakistan was close to re-opening supply lines. But when Pakistan raised its transit fees, negotiations were cancelled. Although U.S. officials say the talks are stalled over technical issues and not the increased fees.

The names of the suspected militants killed in today’s attack are unknown.
