The US intervention has brought about four far reaching changes in the region

But a land incursion will mean death for Egyptian soldiers.

Perhaps more robust military intervention will provoke further atrocities.

And foreign intervention in the French Revolution only fanned nationalist flames.

Monetary policy cannot make safe wealth in the future any more valuable.

That, not China's exchange rate policy, is the culprit.

Their intervention in recent weeks shows a reluctance to let this happen.

But if ad hoc intervention works, why not formalize it?

A lot is at stake all the more so because French intervention is likely to be extensive.

Moreover, prudence does not mean that humanitarian interventions will always fail.

Few suggest that French military intervention was a means to recapture its colonial empire.

America s military interventions in these countries exemplify another key challenge of modern warfare.

John Maynard Keynes once said that monetary policy may work like a string.

China s monetary and foreign exchange policies are now in a state of limbo.

A monetary policy at war with itself cannot long endure.

Indeed, Kouchner s appointment is likely to demonstrate just how vain a hope humanitarian intervention always was.

Russia s intervention has to some extent backfired, strengthening support for a European orientation.

The ECB was right to ignore the exchange rate when it fell to 0.80, and it is right to ignore it today when it is close to 1.20.

Investment decisions are postponed, implying slower growth and an even more precarious fiscal position.

And there may indeed be cases where armed intervention is the only way to stop mass murder.

The moment official intervention is required, everyone runs for cover.

Most Americans care little about China's currency policy or its stance on intellectual property rights.

Only by acknowledging the limits to knowledge can monetary and exchange rate policies have a better chance of succeeding.

There is every reason to believe that we could get the same ad hoc joint intervention going should circumstances warrant today.

A notable exception was NATO's intervention in Kosovo, which was not explicitly sanctioned by the UN.

These countries may exit the crisis their crisis only if monetary policy allows them room to grow.

One route, a currency area without sovereign backstopping, will lead to debt, currency crises, and the eurozone s dissolution.

When the West African Monetary Zone finally is established, the number of currencies in Africa will equal about half the number of countries.

One explanation is to view the intervention as a neo colonial bid to protect a French preserve.

The US military intervention touches all of R2P s bases of legality, legitimacy, and likely effectiveness in meeting its immediate objectives.

Ukraine itself features quite prominently as a keyword, along with conflict related terms like terrorists, intervention, destroyed, soldiers, and fighting.

Over the last decade, trade liberalization and monetary integration supported the expansion of market based financing in Europe.

This channel is ignored for one good reason exchange rate policies are fundamentally of the beggar thy neighbor variety.

Europe needs a monetary policy that views aiding employment growth in northern Europe as more important than continental price stability.

This channel is ignored for one good reason exchange rate policies are fundamentally of the beggar thy neighbor variety.

And, as France s recent intervention in Mali has shown, this ambiguity lies at the root of many of today s most urgent foreign policy problems.

It was NATO s robust military intervention, not European diplomacy, that created the conditions for the end of genocide and ethnic cleansing in the former Yugoslavia.
