There's no "instead" though. Sorry you're not a fan of fighting ISIS, al Queda and the Taliban.....? How would you have fought those enemies "diplomatically?" The WHO
helped China cover up their role in causing the pandemic. If you don't support withdrawal, what would be your response to punish the WHO for their behavior from within? The Paris Climate Accords have no binding enforcement mechanism. What value do you place in it, and how does the US' participation or non-participation affect our ability to reduce our carbon footprint, etc? The US is left relying on the Saudis as a frenemy partner in the Gulf ever since an Islamist coup in Iran that deprived us of our former key ally in the region. How would you "diplomatically" reject both Iran and Saudi while maintaining US leadership without any real regional partners left apart from Israel? Diplomacy is great - if you can enforce it - aka "endless conflicts since 1945."
Many on both sides of the aisle like to claim they support US leadership, but then reject the hard work of leading. Meanwhile, Americans are happier with the US' position in the world than at any point since 2003:
I'm not, but I also understand that diplomacy means nothing without credible strength to back it up. You can't have your cake and eat it too. America can afford to speak softly and project soft power precisely because she has a very big stick for all to see. This is something the US diplomatic corps understands:
Democrat poll respondents now claim to support US world leadership at historic numbers,
a 20 point surge compared to 2010. Most people do. Yet, there seems to be a disconnect when it comes to the military, with those on the left showing the biggest gap:
People can like the general idea of US leadership all they want, but unless they are willing to accept the necessity of the credible threat of force, the international cooperation Democrats favor in huge numbers amounts to rhetoric.
