To determine the role the U.S. should play in the major crisis facing the G20 regarding the value of the Euro in certain Eurozone countries, and to understand the U.S. business exposure if the Eurozone were to collapse, let's break down the question into two parts:

1. Role of the U.S. in the Euro crisis:
The United States, being a major global economy and a member of the G20, can have multiple roles in addressing the Eurozone crisis:

a) Diplomatic role: The U.S. can engage with the European countries facing economic challenges, particularly those within the Eurozone, to understand their specific issues and provide diplomatic support to facilitate resolutions.

b) Economic role: The U.S. can leverage its economic strength to support global financial stability and indirectly assist the Eurozone through measures such as increased trade or investment.

c) Policy coordination role: The U.S. can collaborate with other G20 nations to develop coordinated policies to stabilize currency values, restore market confidence, and support economic recovery in the Eurozone.

2. U.S. business exposure in case of a Eurozone collapse:
If the Eurozone were to collapse, it could have significant implications for U.S. businesses. Here are a few potential impacts:

a) Trade disruptions: The collapse of the Eurozone would likely lead to market turmoil and disrupt trade flows. U.S. companies engaged in exporting to Eurozone countries would face reduced demand, potentially impacting their revenues and profitability.

b) Financial sector risks: U.S. banks and financial institutions may face significant exposure to European debt and assets. Any financial instability resulting from a Eurozone collapse could lead to credit risks, capital losses, and potential liquidity challenges.

c) Currency risk: U.S. businesses with exposure to the Eurozone would face significant currency risk. A collapse could result in a rapid depreciation of the Euro, leading to currency exchange losses for U.S. companies operating in the region.

To mitigate these risks, U.S. businesses can employ strategies such as diversifying their markets, hedging currency exposure, and closely monitoring economic and political developments to make informed decisions.

It is crucial to note that the specific role of the U.S. and the level of business exposure would depend on the nature and extent of the crisis and various economic and political factors at play.
