Iran just attacked Israel.

That, according to the U.S. will be met with “severe consequences for Iran.”

In fact, according to a recent tweet, “IDF Spokesman Rear Adm. Daniel Hagari says Israel will respond to the Iranian missile attack on the country.”

“We are on heightened alert on defense and offensive, we will protect the citizens of Israel. This [missile] fire will have consequences. We have plans, and we will act in the time and place that we choose,” he added.

With support from the U.S., we’ll see even more spending on defense, which will serve as a key catalyst for defense stocks, and ETFs such as:
