MOSCOW (AP) — Russian President Vladimir Putin said Friday that Moscow could adopt what he described as a U.S. concept of using preemptive military strikes, noting it has the weapons to do the job, in a blunt statement amid rising Russia-NATO tensions over Ukraine. “We are just thinking about it. They weren’t shy to openly talk about it during the past years,” Putin said, referring to the U.S. policy, as he attended a summit in Kyrgyzstan of a Moscow-dominated economic alliance of ex-Soviet nations. For years, the Kremlin has expressed concern about U.S. efforts to develop the so-called Conventional Prompt Global Strike capability that envisions hitting an adversary’s strategic targets with precision-guided conventional weapons anywhere in the world within one hour.
