G7 Summit Tests Cross-Border Security Without a Unified Command

Switzerland deployed 4,000 troops to block protesters using its territory as a staging ground. France controls its side under the Schengen system. Recent clashes in Geneva signal organized opposition ahead. The arrangement reveals how difficult it is for two countries to synchronize defense while staying sovereign.
