Turkey: Unlikely to weaponize for strategic and political reasons. Like most of the region, Turkey's stated goal for developing a nuclear program is to meet its energy needs. But Turkey's nuclear journey has been a long and difficult one so far.
Ankara has faced a number of regulatory challenges in the development of its nuclear program. As is the case for most of the region's nuclear newcomers, Turkey's leading nuclear partner is Russia's Rosatom. The two countries concluded a so-called "BOO" [build, own, and operate] agreement. At the current pace, Turkey’s first nuclear power plant won’t be ready before 2022. The severe impact of sanctions on the Russian economy may further slow progress. In addition to Russia, Turkey is also working with a Franco-Japanese consortium that would build a second plant in the Black Sea town of Sinop by 2023.
To date, Turkey denies any plans to develop an enrichment or reprocessing capability. In addition, Turkey has entered a safeguards agreement with the International Atomic Energy Agency (IAEA) and has agreed to the Additional Protocol, putting Ankara’s program under strict IAEA monitoring and making it difficult to divert fissile material for use in a weapons program.
Aside from the technical limitations, there are strategic and political reasons why Turkey isn't likely to weaponize. As a member of NATO and a US ally, Turkey benefits from Washington's nuclear umbrella. Its defense needs are met without it having to go through the trouble of developing its own nuclear capability—a resource-heavy endeavor for a country struggling to build a nuclear energy program. A military nuclear program would most likely result in a loss of the US as a strategic ally and the NATO nuclear umbrella.
