NATO expansion sparks tension with Turkey, Hungary, and Russia.

Turkey and Hungary are blocking Sweden's path to NATO membership, with analysts not expecting Turkey to ratify Sweden's application until after its May 14 election at the earliest. Turkey has accused Sweden of not taking its security concerns seriously and harboring members of terrorist groups, while Hungary is angry about Swedish criticism of Prime Minister Viktor Orban. Sweden has received assurances of support from countries including the United States, Britain, and Germany, and its security position is better now than prior to its application to NATO.
