  • New warfare tactics – Embedded anti-air defenses and remote platforms inside Iran show modern conflict evolution.

  • U.S. weighs in more overtly – Trump took a hands-on role, signaling that future Middle East conflict may involve the U.S. directly.

  • Regional stability in flux – Oil markets and geopolitics shifted after 12 days of intensified conflict.

  • Diplomacy rests on knife-edge – The ceasefire is fragile. Long-term peace depends on renewed talks, transparency, and trust.
