Regardless of the West's mistakes, I think it is important not to ignore Pakistan’s role in Afghanistan.

For decades, Pakistan has served as a sanctuary for the Afghan Taliban, who have often crossed the countries’ rugged, 1,660-mile border with ease. Officials have acknowledged that Taliban fighters maintain homes and families in Pakistan, at a safe distance from the battlefields …
Pakistan has leverage that it is not bringing to bear, government officials in other countries say. It still allows Taliban leaders free movement into and out of the country and continues to serve as a safe haven where fighters and their families can receive medical care, they say.
Some critics, particularly in Afghanistan, accuse Pakistan of actively supporting the Taliban’s offensive, saying that the insurgents could not have mounted such a large effort without assistance. On social media, the hashtag campaign #SanctionPakistan has gained popularity in Afghanistan and among the diaspora.

So, the more pressure is put on Pakistan and other rogue states in the region, the better.
