Interested in joining new-age defense firms so we may prevent tomorrow's conflict. Geopolitical balance is being threatened in all parts of the globe, and we are seeing that, today, being the strongest nation isn't the decider of who wins battles - it's the one who can survive death by a thousand cuts
Born and raised American
