A great pitch for the book. Bacevich presumably included the Balkans because of the character of the intervention.
The traditional justification for US involvement in the Mid East is to secure the supply of oil, which will remain true for many years despite the use of renewable energy & of fracking. (If only the 1st Bush had committed as many resources towards developing renewable energy as towards munitions…)
Does Bacevich address what to do about Qaeda & about ISIS/ISIL? Whatever should have done differently before, they exist & are unlikely to ignore the USA just because we withdraw from Iraq, Syria, and Afghanistan.
