Ninety-two years ago Thursday, she breathed her last breath. At 2:20 a.m., to be exact. More than 1,500 men, women and children died.

It was the worst marine disaster in peacetime history. The unsinkable sank. The unthinkable happened.

Man's most boasted achievement at the time was relegated to a broken heap of wreckage at the bottom of the Atlantic at the time.

The Titanic.

The symbol of everything man could do right. A reminder of everything man could do wrong.

It was our greatest achievement. It became our greatest embarrassment.

We are sometimes a cocky species. Assuming we have all the answers, but forgetting to ask any of the questions.

We make assumptions about ships that cannot sink and today, wars that we supposedly cannot win.

We were wrong about ships then. I like to think we're wrong about wars now.

Sometimes the crowd gets ahead of itself, assuming based on press at the time, that so it will be for all time. Ships that will glide safely into the night. Troops that will be ravaged into many a night.

It's why people who party during market bubbles, refuse to see the bubble. And why those who disparage bear markets, refuse to see the bull. Because a lot of the time, what we think "is" bull. And like the Titanic nearly a century ago... all wet.

We get it wrong -- so often, so much -- that you'd think we'd be so careful making any assumptions at all.

We got it wrong on a ship that couldn't sink. I think many are getting it wrong on a war the world's assumed can't be won.

That's not just me saying that. That's a thing called history reminding me of that.
