Navy May Use Mine-Detecting Dolphins In the Straight of Hormuz

New submitter cervesaebraciator writes "The Atlantic Wire reports that the Navy has a tested solution to the possible mining of the Strait of Hormuz. The Navy has 80 dolphins in San Diego Bay trained to use their own sonar to detect mines. When they find the mines, the dolphins drop an acoustic transponder nearby, so that human divers might return to defuse it. Retired Adm. Tim Keating cannot say, however, whether the dolphins will be used in the Straight." The Obama administration has reportedly warned Iran that closing the Strait would provoke an American response.

Countries have a perfect right to develop nukes if they want, and cut off inspections that they are only working towards nuclear power, and all it does is get them kicked out of the nuclear weapon's treaty, which means many countries won't sell uranium to them. That's it. It doesn't give anyone the right to attack them, or be 'provoked' into a war with them.

    I think people have somehow gotten confused since the Iraq war and think developing nukes are 'illegal', but Iraq signed a surrender in war saying they wouldn't develop nukes, so, if they actually had been doing so, it would be a violation of the surrender and the war would be back on. Iran is not anywhere near the same situation.

    However, threatening to bomb Iran in violation of international law is illegal. I don't mean actually bombing Iran, although that's also illegal...just threatening to attack countries over internal matters is actually illegal. As is planning to do so. It's a crime against peace. Somehow, that doesn't count as 'provoking'.

    But, if Iran does what is mostly within international law, closing of its own waterways to transit passage of countries threatening it, that is also 'provoking'. Countries are supposed to allow passage of ships through their waters as long as they don't stop, but they can stop that when, for example, people keep threatening to attack them. (And they can certainly keep out warships of countries that keep threatening them!)

    To summarize: Iran doing things we don't like that are possibly falling short of their treaty obligations, but are not in any way 'illegal', that's 'provoking' us. The US committing the outright war crime of planning and threatening to bomb them to change their internal behavior, why, it's crazy to think Iran might not like that.
