war "War is hell," said Civil War General William T. Sherman, no matter what it's called. Avoid euphemisms like armed conflict, armed intervention, a military solution, police action, uprising, use of force. Capitalize the word when part of the name for a specific war: World War I, World War II, the Cold War, the Korean War, the failed Vietnam War, the endless Gulf War. Also, if one country invades or attacks another country, there's no war until the other country starts defending itself, as it has a right to do.
Also, beginning a sentence with what adds needless words. Delete it and simplify: I long for butterflies. I long for the butterflies. Finally, because what is often the first word in a question, beginning a sentence that's not a question with what may confuse some readers.
To test for correctness: Who equals he, she or they while whom equals him, her or them. Replace who or whom in the sentence with one of those pronouns. If it sounds wrong, it probably is.
wreak havoc Overstated, vague, wordy and sometimes misspelled. Simplify. Omit and describe the damage, problems, confusion and chaos instead. Or try using demolish, injure or ruin instead. And don't spell it wreck havoc, work havoc or reek havoc.
