"It is my view that we cannot conduct foreign policy at the extremes"

In this quote, Joe Biden is expressing his belief that diplomacy should not be carried out in an extreme manner. He is recommending that taking severe actions or having severe views can be detrimental to reliable foreign policy. Instead, he thinks that a more moderate and balanced approach is required in order to effectively navigate relationships and interactions with other nations. This could mean finding commonalities and compromise rather than taking hardline stances. Biden's declaration highlights the importance of diplomacy and cooperation in diplomacy, rather than depending on extreme measures that could potentially create more dispute and damage.
