Here's a belated offering to the 2019 predictions party. A friend who is well up on the Americas suggests that both the Donald and Brazil's Bolsonaro will be in dire need of foreign-policy distractions in the months to come. Fitting the bill nicely would be an invasion of Venezuela. This, he predicts, will be conducted by Brazil and Columbia, with US topcover if not actual regular military engagement.
While we have our tin hats on (proper ones, not the tinfoil variety, you understand); that would sit well with cross-border interventions by both Russia and China. There is of course a history of countries with itchy trigger-fingers taking their cue from events several thousand miles away. Busy times ahead at the UN? Well what's the point of having a veto if you don't use it from time to time.
Getting ahead of ourselves a bit, here: but perhaps Jezza could raise an International Brigade for Venezuelan deployment? I am sure that Momentum members would shape up into effective troops: Corbyn Companies and Snowflake Battalions for the defence of socialism in foreign parts. It'll all be over by Christmas, boys and girls.
