The United States has alerted European allies, including the UK and Poland, about significant delays in arms shipments as the conflict in Iran continues to deplete military stockpiles. Officials from Norway, Finland, and Estonia have also reported that they may experience delays in receiving US defense supplies. The situation raises concerns among NATO allies who rely on US military equipment, as diminishing stockpiles could impact support for ongoing conflicts, including the situation in Ukraine. This crisis highlights the interconnected nature of global military supply chains, as European nations brace for potential shortages following US warnings.
