with nuclear arsenals

at each other. It is not commonly used to refer to a group other than a government
, such as a terrorist
organization using nuclear weapons to attack a target, or to refer to a nation with nuclear weapons
firing them at a nation without nuclear weapons. It usually refers to delivery by airplane

Most analysts currently believe India and Pakistan are the two nations most likely to be involved in a nuclear war. It even seems likely that none of the major world powers would use nuclear weapons in that event - at least not immediately.
The most likely catalyst for such a war is the tension over Kashmir, a region which has been claimed by both countries since they became seperate nations.
A nuclear war would have long term effects on both participants and at least some uninvolved bystanders, perhaps after the original causes of the war were forgotten, as large areas become contaminated by radioactivity, and radiation as carried to different places by air and water circulation.
