Rogue Flag Book by ROBERT. HRZIC

In the midst of a new Cold War, a deranged populist steals nuclear warheads from some of the UN Security Council members in order to form his own sovereign micronation. This pushes tensions to breaking point. Irish G2 station chief Connor O'Hara must lead a group of operatives to find the stolen warheads before this second Cold War turns into a hot shooting war... one with three nuclear armed sides.
