Russia - having sat across the table from Vladimir Putin, it's pretty clear when you meet him that he has an almost limitless ambition for power. And he's been very good at acquiring it - political power, economic power, military power, territorial power.
I think our nation is at a pivotal point. Too many people fear that we are losing the sense of limitless possibility that has always defined this nation.
Human potential is the only limitless resource we have in this world.
