Flight plan: XA:12. Actual block: XA:40. No break for two pilot crew during return from [overseas] where quality/length of sleep period is always poor at best with a 25 hour layover. Same flight last week scheduled XX:59; blocked [20 minutes later] with low fuel due to unexpected headwinds. Peak decision making is required approaching ZZZ; especially if weather is present. Peak decision making not available with two man crew after 8 hours of flying and a 25 hour [overseas] layover.
