I
used to think war was simply stupid and useless. In an absolute sense,
this is true: If everyone everywhere simply refused to participate in
war, all of us would be better off, and armies would be unnecessary. But
this is about as helpful as noting that we'd all be better off if
everyone decided not to commit crimes, thus making police unnecessary.
No one would argue the police should be abolished in order to stop
crime. Similarly, one country deciding not to participate in wars would
not prevent them.
But it's worse than all
that because the police analogy is a poor one. In the world as a
whole, there is no police force. There isn't one authortiy, subject to checks
like judicial review, that enforces laws established through democratic
processes. A better analogy might be the American frontier or wild
west: a place where each person was responsible for his
own safety and vigilante justice was the norm. In such a place, everyone had to be armed to defend himself.
The international
system is anarchic like this. If a country gets into trouble, it can't
call the police. The only thing it can do is call an alliance partner
and hope that partner will be willing and able to help. As the most
powerful country in the world, America is an alliance partner to many,
like Japan, Australia, Taiwan, and South Korea in Asia-Pacific, or Saudi
Arabia and Israel in the Middle East.
It is these alliances
that have helped keep the world fairly quiet over the past 60-odd years:
Japan could have nuclear weapons and a powerful military, but it does
not, because it trusts its alliance with America to keep it safe, even
as its next door neighbor China grows more powerful and belligerent each
year. The same goes for all the other countries allied to America.
American military might dwarfs the rest of the world in part because
America is committed to protecting so much of the world and in part
because so much of the world trusts American protection and therefore spends less than it otherwise might.
This is not a selfless act: America has much to gain from a
world at peace, and much to lose from war, especially with the
commitments it has. This stability survives on trust, however, which in return
relies on America's reputation. If Japan stopped trusting America's
ability or willingness to protect it, as a recent push to change its
constitution to allow it to have a "real" military suggests it is
already beginning to do, it might build up its military and issue
deterrent threats of its own. It might even seek an atomic weapon as a
guarantee. All of this would dangerously increase tensions with China and might make other neighbors nervous, too. Trust would begin to breakdown.
Likewise, if Saudi Arabia did not trust American security guarantees,
it would likely likely beef up its own military power out of fear of Iran, encouraging others in the Middle East to follow suit
out of fear of Saudi power. Lack of trust in America's ability and/or
willingness to protect its allies would lead to destabilizing chain
reactions.
This brings me to Syria. President Obama swore that the
use of chemical weapons would not be tolerated. Had he said nothing,
perhaps America could argue it had "no dog in this fight," but he made a
very public promise, so America's reputation is at stake and with it,
all the stability-enhancing alliances I mentioned above.
Few would doubt America's commitment to protecting itself
if directly threatened, but its commitment to its allies is less
certain. Obama has promised to prevent Iran from
getting a bomb using whatever means necessary. The hope is that this threat alone will be
enough to force Iran to back down. But the efficacy of that threat relies on America's reputation. If America is unwilling to attack Syria when it has made a
highly public commitment to doing so, its claim to be able and willing to stop Iran from getting the bomb looks ridiculous.
Furthermore, once America is no
longer seen as an important ally, its influence will shrink, reducing
its ability to impact other world events in a way favorable to it,
including drives for democracy and free trade. The result would be a
less stable world with a diminished America lashed to the helm, steering an increasingly uncontrolled course. This is
why limited action on Syria is needed. Not to end the war, topple the
regime, or alleviate the humanitarian crisis there, but, believe it or
not, for even bigger reasons that impact the entire world, rather than
just one tragically war-torn part of it.
