ISIS remnants are looking for new rear-area bases in which to regroup, train, equip and then move out again.
The Taliban is just as much a threat to the West (esp. with their control of a lot of the poppy growing areas/heroin production in Afghanistan.
Where do you think much of the heroin in Europe and even the US comes from, K-Mart? Mexico is basically the only country in the western hemisphere that produces heroin. Red China, Burma/parts of Thailand and possibly No. Vietnam are the main producers of heroin in Asia besides Afghanistan.
ISIS, Al Qaeda and other affinity groups will traffic in drugs to raise money for arms and supplies, even in Central Africa, northern Africa and moving it through Lebanon/Syria/parts of Iraq/Iran.
They are the enemy and must be checked. I would prefer nuked but that’s just my choice of options.
The poppy yields have increased significantly since we have been stationed there. Care to explain that?
