Firstly, I don't think the West is that much against rebuilding, especially when the original was suddenly and tragically destroyed: just look at all the restored old city centers of Europe. This is more akin to healing a wound (of societal memory) to its original state. However the stance is rather different for reviving long lost buildings, mostly coming from the architecture/archeological scene, not the general public. Their (kinda valid) argument is that these developments can never ever be authentic, and restoring them is anachronistic, driven by nationalism, and the goal is often to restore not only the place but the views of that time. A modern work - that would play homage, or provide a different new meaning - is viewed as actual progression.
