Can the U.S. remain secure and prosperous if Europe’s security collapses?
How would China’s military and economic support for Russia shift the balance of power if the U.S. leaves NATO?
Should NATO continue to expand, welcoming new members — or pause enlargement?
What is the value of European strategic autonomy — does it strengthen or weaken transatlantic security?
