Richard Nixon announcing an invasion of Cambodia in 1970 surprised many people because he had promised to end the war in Vietnam. His campaign called for an end to the war.
This announcement came as a surprise because this did not look like "vietnamization". They thought Nixon was trying to "win" the war with more American troops and a new battleground. They believed the US should not be invading a new country and widening the war.
Because they did know it was going to be an invasion. But they did not know where or when.
The 1970 invasion of Cambodia came as a surprise for two reasons. First, Nixon did not declare war on Cambodia so he didn't ask permission from Congress. He simply made it a part of the larger Vietnam War campaign. Second, it came at a time when Nixon was talking about slowly scaling back U.S. involvement in Vietnam and many saw this as doing just the opposite by widening the scope of the war.
Stalin was surprised by the German invasion of the Soviet Union because he had signed a non-aggression pact with Germany, known as the Molotov-Ribbentrop Pact, and believed that Hitler would not attack.
At least one reason was because the Ho Chi Minh Trail went through parts of Cambodia, so the invasion of Cambodia was less of an attempt to attack the Cambodians and more an attempt to disrupt the flow of Vietnamese traffic along the trail.

President Nixon lost congressional support due to American military activities in Cambodia and Laos, which had continued after the cease-fire in South Vietnam went into effect, ended in 1973 when Congress cut off funds.
Because Cambodia is a developed country. And Cambodia is a poor country,and US wants to help poor countries.
