一图看懂｜为何伊朗说美国想打通霍尔木兹海峡是“自杀式行动”？

“为何” is a formal written way to say “为什么” (“why”). It is often used in news headlines, articles, and formal writing to ask about a reason or cause.

“说” can introduce reported speech, opinions, or judgments. After “说”, a full clause often follows to show what someone says, thinks, or claims.

“想” before a verb expresses intention, desire, or plan to do something. It is one of the most common ways to say “want to” in Chinese.

“是” is used to identify or judge something as belonging to a category or having a certain nature. In this sentence, it marks the speaker’s evaluation of an action.

In headlines, “一 + measure word + verb” can mean “with one ... , understand/see ...”. “一图看懂” literally means “understand it with one picture,” a common media headline style.
