US attempts to pressure countries bordering Iran to close their borders have so far been unsuccessful, as Turkey, Iraq and Pakistan have rejected Washington's demands. ".
Turkey has largely refused to change its border policies, and Iraq has rejected U.S. requests to close all but two border crossings, according to the New York Times. This refusal thwarted Washington's efforts to tighten the economic blockade on Iran, prompting the Trump administration to establish a task force called "Iron Gates" to combat cross-border trade and smuggling.
