Yes, the United States Military will defeat ISIS. It is only a matter of time. ISIS is the biggest threat to the United States (besides itself) that needs to be dealt with, and it will definitely be dealt with. The United States has a great track record when it comes to hunting down terrorists.
The Islamic State, more commonly known by the acronym ISIS, has inspired fear throughout the world. They have committed terrorist acts and have captured much of Syria, inspiring a massive exodus of refugees. In return, the American military has amped up their agenda to destroy these terrorist cells. It's only a matter of time before they are able to do so, given the massive amounts of military intelligence that the American military has.
Just like in Vietnam the us will lose and aside from that the US isn't fighting a country but an idea, a political and religious radical group . ISIS is like the vietcongs but with the exception they are spread out more and with technology out there people can join them from half way across the world. The only true way to defeat ISIS is letting the middle east take care of the problem for themselves no matter if a genocide , religious and ethic cleansing happens but eventually it 'll get better but as long as the west keeps intervening in the middle east it'll create more problems
The US military will not defeat ISIS for a couple of reasons. First, the current administration is not allowing the military to use its full force and effect to carry out its mission. If you don't play a game to win, you will not win. Second, and more importantly, the enemy is difficult to identify. They look just like you and me...like regular citizens. The only way to eradicate them is to destroy everyone, including innocent civilians.
No, the U.S. military is unlikely to defeat ISIS. While the terrorist organization may be weakened somewhat or lose territory, it is like a cancer. Terrorism is a type of belief system as well as a violent practice, and it spreads rapidly among people who are discontented with the world power structure.
