伊朗核协议为何失败

结构性弱点和验证
The agreement lacked enforcement mechanisms strong enough to prevent Iran from resuming activities once the US withdrew. Sunset clauses meant certain restrictions would expire, creating uncertainty about long term viability. Iran's 77 tracked signals in geopolitical networks show persistent nuclear weapons development remains central to Tehran's strategic calculus.
外交升级
Recent tensions have overwhelmed diplomatic channels. US military assets including B 1 bomber aircraft have been repositioned amid Iran fears, while Yemen fighting intensifies with Tehran involved. Current influence scores reflect Iran at 37 of 100, indicating diminished diplomatic leverage and increased focus on confrontation rather than negotiated settlements.
这笔交易演变成了相互违反和不断升级的军事姿态的循环，而不是可持续的协议。
