Notes of Prof. Loch Johnson's well-received presentation, on the US in an uncertain and dangerous world, have been uploaded to the AWAC.US web page: http://political-science.org/WACA/AWACNotes17-18.htm
Johnson laid out a multi-tiered threat assessment for the US. Then he called for a shift from the excessive and unproductive use of military force and aggressive use of intelligence assets for covert operations -- towards greater use of diplomacy and State Department resources.
