All-source intelligence is like a big puzzle. Imagine you have a lot of puzzle pieces in front of you and your job is to put them together to make a complete picture.
Now, instead of regular puzzle pieces, imagine you have lots of information about something you want to understand, like a person or a country. This information can come from lots of different sources, like news articles, social media posts, interviews with people who know about the topic, government reports, or even satellite images.
Just like with the puzzle, your job is to take all this information and put it together to make a better picture of what is happening. You might notice things or connections that you wouldn't have seen if you were only looking at one source of information.
For example, imagine you are trying to understand a foreign country's military capabilities. You might look at news articles about their military parades or speeches made by their leaders, but you might also look at satellite images of their military bases, interviews with experts on the country's military, or even information leaked by spies or informants.
When you use all of these sources together, you can create a very detailed understanding of the country's military capabilities, and you can use that information to make decisions about how best to interact with them.
All-source intelligence is important because it helps leaders make more informed decisions. By looking at lots of different sources of information, they can get a better idea of what is happening and what might happen next, which can help them protect their country or make better policy decisions.
