It's good to know that President Trump is open to change. As a former Trump aide stated, "He has a general reaction to something, then after he does a lot more homework on the situation, he can change his view" ["Trump's about-faces please many Republicans," news, April 14]. His flexibility and willingness to act in the face of moral outrage were revealed in his reaction to the chemical weapons attack ordered by Syrian President Bashar al-Assad that killed "small and helpless children and babies" ["Trump reversal on NATO: 'It's no longer obsolete,' " news, April 13].

I sincerely hope that as Mr. Trump learns more about famine in South Sudan and near-famine in Yemen, Somalia and Nigeria, he will lead and quickly restore the humanitarian aid and requested emergency U.N. funding that his budget proposals have put at risk ["Wars have left 20 million people on the brink of starvation," The World, April 12]. Those events, mostly brought about by war, threaten 20 million people, the most at risk since World War II. Cruise missiles won't solve this, but U.S. leadership, funding and international resolve can.
