You live in the age of interdependence. Borders don't count for much or stop much, good or bad, anymore.
...the fact [is] that our borders leak like a sieve: those things cannot be permitted to continue in good conscience.
We can't afford to lose control of our own borders or to take on new financial burdens at a time when we are not adequately providing for the jobs, the health care and the education of our own people.
To realize the full possibilities of this economy, we must reach beyond our own borders, to shape the revolution that is tearing down barriers and building new networks among nations and individuals, and economies and cultures: globalization. It's the central reality of our time.
