whata tense is the verb "are allied"? to be+past participle, what does it mean?

Question

In just the past 24 hours the situation in Syria has unraveled in an
astounding turn the Syrian Democratic Forces who are allied with the
US in the fight against ISIS until just over a week ago now have a deal
with the Syrian government, a former enemy and an ally of Russia.

Answer 1

فکر کنم اشتباه در خود متنه. زمان فعل با قید نمی‌خونه. قطعاً are allied حال ساده‌ست، اما until just over a week ago یعنی تا کمی پیش از یک هفته قبل، که می‌شه زمانی در گذشته! درست اینه که از فعل گذشته‌ی ساده استفاده بشه: were allied.

فعل  to be allied with بعنی متحدبودن با.
