But, as everyone now knows, the "worst economic crisis in history" never happened.

This crisis could not have happened without the rating agencies.

The crisis, and the abrupt end of a season, had happened somewhere else.

A crisis may happen only if the nerves of the leaders give way.

If another crisis happened, the groups would be ready.

"If they wait until a crisis happens, it's almost too late," he said.

It's possible that the crisis would have happened even without deregulation.

Some Democrats say the crisis would have happened eventually even without the terror attacks.

A financial and economic crisis such as the one we are currently experiencing must never happen again.

I sometimes wonder whether the current financial crisis is happening on some other planet.
