Tiny, high defence-spending EU and Nato member Estonia, which neighbours and fears Russia, experienced a slap in the face by the US this week regarding defence capabilities. Because of its own needs in the war with Iran, the Pentagon told Estonia it would have to delay delivery of six units of a high-tech weapons system (the High Mobility Artillery Rocket System) that Estonia had contracted to buy from the US government. The US Embassy in Tallinn had called the purchase "one of the most significant capability upgrades in Estonian military history." Estonia is now left feeling exposed.
