If anything the developments of the past week reinforced that ending US military involvment Afghanistan now was the right decision.

American troops cannot and should not be fighting in a war and dying in a war that Afghan forces are not willing to fight for themselves.

以上是拜登原话。

请教老师，If anything the developments of the past week reinforced that ending US military involvment Afghanistan now was the right decision.

这句话中if anything 是什么成分？这句话主谓宾分别是什么呢？另外，should not be fighting in a war and dying 中的dying 应该是should not be dying...die是瞬间动词，

怎么理解这里的dying 含义和用法？

should be doing 中表示将来事件，对do是否为持续还是短暂动词有无要求呢？如果是短暂动词的doing, 如何理解should be doing 将来事件呢？
