If the Iranian regime survives a no-fly zone over Iran in its core Persian-speaking region (the ethnic periphery will no doubt revolt) will a no-fly zone crucially permit continual air raids against Iranian nuclear installations on a regular basis. This will offer significant operational advantages when implementing air strikes against the Iranian nuclear weapons program. “Mowing the grass” on a regular basis is preferable to a major operation every five years or so without a no-fly zone which leads Tehran to order mass terrorist attacks against the nation that launched the operation. “Mowing the grass” on a regular basis as part of a no-fly zone is much preferable because it avoids international confrontation outside of Iran and rather maintains a continual conflict inside Iran itself. This will also effectively prevent Tehran from rebuilding its nuclear weapons program after it has been destroyed. These are yet other strong arguments why a no-fly zone over Iran is an American vital national interest indeed.
