Bacevich isn't the only one who presented testimony the 15th on A New US Grand Strategy:

James Dobbins, RAND
....Having served under eight presidents through seven changes of administration, I have come to view these transitions as periods of considerable danger, as new and generally less experienced people assume positions of power with mandates for change and a predisposition to denigrate the experience and ignore the advice of their predecessors. America needs a grand strategy that helps it bridge these troubled waters, one that enjoys bipartisan support and is likely to endure. One key criteria for judging any newly announced grand strategy, therefore, is whether it is likely to be embraced by successor Administrations. In this respect, Napoleon’s advice with respect to constitutions may prove apt: that they be short and vague.
Barry R. Posen, MIT
The United States is a powerful country. Nevertheless, it is not as powerful as the foreign policy establishment believes. Political, military, and economic costs are mounting from U.S. actions abroad. At the same time, the U.S. has paid too little attention to problems at home. Over the last decade Americans became accustomed to a standard of living that could only be financed on borrowed money. U.S. foreign policy elites have become accustomed to an activist grand strategy that they have increasingly funded on borrowed money as well. The days of easy money are over. During these years, the U.S. failed to make critical investments in infrastructure and human capital. The U.S. is destined for a period of belt tightening; it must raise taxes and cut spending. The quantities involved seem so massive that it is difficult to see how DOD can escape being at least one of the bill payers. We should seize this opportunity to re-conceptualize U.S. grand strategy from top to bottom.
Mitchell B. Reiss, William and Mary Marshall-Wythe School of Law
As a first step, I strongly urge the Committee to hold hearings on developing a strategy for sustaining and enhancing America’s economic power. Such a strategy would include the following issues:

- Reducing the national debt, which now stands at record levels, and has placed great stress on the middle and working classes;

- Tackling the coming crisis in entitlement payments (especially health care); driven by the “bow wave” of the boomer generation, U.S. citizens 65 and over will increase by a projected 147% between now and 2050;

- Reforming immigration laws to ensure that highly skilled and motivated people can come to the United States to work, create jobs and receive an education;

- Revitalizing our industrial infrastructure; and

- Developing a new national energy strategy to reduce our dependence on foreign oil, including greater investment in alternative energy sources.

These are just a few of the hurdles that we will have to surmount in the coming years if we wish to keep America strong. Undoubtedly, there are others. None of them will be easy to accomplish. But it is important to remember that small countries do not attempt such things. Only great ones do.
