Storm Warning?

If we were going to attack Iran (or cooperate with or simply accept an Israeli attack), it makes sense that we'd let China know that it is coming. Not that we'd let them know when (they might warn Iran). But out of common courtesy for a rising power, we'd give them time to prepare to cope with the loss of Iranian oil.

So China might do this (tip to Instapundit):

China has "started filling its emergency petroleum reserve at Lanzhou in the nation’s northwest, according to an official at the nation’s largest crude producer."

Some things make sense. What if China isn't the only country buying oil now? Just in case?

But I've thought oil reserve issues made sense before, and here we are.
