Part 1. Definition
You will be given a context and a verb separated with a newline character, and you have to answer if the given verb can be anchored in time or not. We say a verb can be anchored in the real timeline if and only if a verb happened in the past, is happening now, or is guaranteed to happen in the future. The output should be "Yes" if the verb can be anchored in time and "No" otherwise.
Part 2. Example
It was followed by Denmark, Norway, Germany, France, Greece, Luxembourg, Spain, Britain, the United States, Iceland, Belgium, Italy, Portugal and Turkey. NATO decided at last year's Madrid summit to (invite) the three eastern European countries to start accession talks.  
 Verb: invite
Answer: No
Explanation: This is a good example. The "invite" is not anchorable. Although NATO decided to invite them, they haven't invited them yet, and it's not guaranteed to happen in the future. They might change their decision later.
Part 3. Exercise
The enlargement of NATO from 16 members to 19 has been one of the administration's foremost foreign policy goals, one that grew out of a desire, its proponents said, to cement the democratic gains made in the former Warsaw Pact countries after the collapse of communism 10 years ago. But the policy also faced critics, who argued that welcoming these three new countries would draw a new line across Europe and (antagonize) the Russians.  
 Verb: antagonize
Answer:
No
