What if an extra-terrestrial force attacked Earth? What might that look like and how will the people of Earth respond?

Experts reveal what could motivate alien invaders to attack Earth, and speculate on how the attack might play out, the strategy alien invaders might use, and the most effective ways for humans to respond.
