The minimum you must know
Guatemalans care deeply about peace. This is obvious from United Nations presentations by the country's leaders, including a very eloquent address at the 79th General Assembly by President César Bernardo Arévalo de León. (The entire presentation patterns "peace" exceedingly well. An excerpt appears below.)
President
César Bernardo Arévalo de León
United Nations 79th Session
The United States has already great and continuously improving relations with Guatemala. And the U.S. is struggling to control the U.S. southern border with Mexico, which experiences a substantial influx of migrants. Guatemala isn't the source of the immigration challenges for the United States. In fact, Guatemala is in exactly the same position as Mexico and the United States with respect to migrants. But the U.S. has an interest in helping Guatemalan borders to remain secure because of the country's northern border with Mexico. That makes Guatemala strategically important from the perspective of the United States.
Immigration is slowing considerably nowadays. But Guatemala used to be very suddenly overwhelmed with countless migrants, particularly when Venezuela was initially prevented from participating in the global economy. Many Venezuelans left their home country to seek work abroad, including in Guatemala, Mexico and the United States. Venezuelans used to overwhelm Guatemalan cities without notice. Some settled while others proceeded north through Mexico to the United States. Guatemala developed a very efficient immigration policy as a result. Probably the government privately hopes for improving U.S. - Venezuelan relations to reduce this burden.
Guatemala is a naturally beautiful country that is at peace with all other ones. The government is very well regarded globally. Guatemala has been burdened by immigration from United States foreign policy, and deserves a helpful attitude as a result. It's clearly a stabilizing democratic diplomatic influence on the region and beyond.
