Tumbleweeds have taken over world and taken over roads in US. Why is it so difficult to grow in our country?

Why is tumbleweed so common in United States? Tumbleweed is common in Gobi. They are very similar to balls. They roll on ground like snowballs and they are very big. There must be 2 individuals who can withstand it. . For their active growth, their growth environment must have a lot of water. If they lose water, they become very dry.
Then they slowly break away from roots, curl up into a ball and, driven by a strong wind, roll over and sow seeds in ground. So how did this windblown grass get to United States? Around 1870s, some people from Russia migrated to western Central Plains of United States and brought with them flax seeds that could be used to make clothing and food.
I planned to farm like in their hometown, but suddenly seeds they brought were mixed with tumbleweed seeds that grow wild in United States. It took 15 years to they spread throughout United States. . The main reason is that there are no natural enemies of tumbleweed in US and there are very few pests in the US.

The tumbleweed is thick and big and accidentally cut hands of cleaners, so cleaners have to wear gloves and spend a lot of time cleaning each time so that car owners can drive through smoothly, which is very upsetting for owners. Delay a lot of things.
In addition, tumbleweeds also cause damage to crops. Tumbleweeds are full of bacteria that can cause pests, eating away local crops, which is why some Americans are worried about wind. extremely disgusting.
