Solution:
1. after downloaded the text file, we realized this challenge is **whitespace steganography**.

2. we can use SNOW program in windows to decrypt it [SNOW Program](http://www.darkside.com.au/snow/) or stegsnow in linux to decrypt it

```
windows command:
SNOW.EXE -C cold_war.txt

linux:
stegsnow -C cold_war.txt

flag{do_not_use_merriam_webster}
```


3. we found the flag is 'flag{do_not_use_merriam_webster}'

FLAG: **flag{do_not_use_merriam_webster}**
