By JON GAMBRELL, Associated PressDUBAI, United Arab Emirates (AP) — President Donald Trump has signed an executive order vowing to use all measures including U.S. military action to defend the energy-rich nation of Qatar — though it remains unclear just what weight the pledge will carry. Qatari officials did not immediately respond to a request for comment on Trump’s order. However, the Qatari-funded satellite news network Al Jazeera prominently reported about it Wednesday under the headline: “New Trump executive order guarantees Qatar security after Israeli attack.”The true scope of the pledge remains in question. Qatar, a peninsular nation that sticks out into the Persian Gulf, became fantastically wealthy through its natural gas reserves. President Joe Biden named Qatar as a major non-NATO ally in 2022, in part due to its help during America’s chaotic withdrawal from Afghanistan.
