“Prime Minister Kishida stated that, as the G7 Presidency, Japan would maintain the unity of the G7 in imposing strict sanctions against Russia and providing support to Ukraine,” a joint statement from the two leaders said.
Don’t expect any cracks in G7 unity over Ukraine at the summit.
I don't get what the exact meaning of 'cracks' is here. I looked it up in the free dictionary:
a. A partial split or break; a fissure: cracks in the basement wall.
b. A slight narrow space: The window was open a crack.
c. Informal the fissure between the buttocks.
- A defect or flaw: cracks in the argument; a crack in his composure.
- A sharp snapping sound, such as the report of a firearm.
- A sharp resounding blow: gave him a crack on the head.
- A breaking, harshly dissonant vocal tone or sound, as in hoarseness.
- An attempt or try: gave him a crack at the job; took a crack at photography.
- A witty or sarcastic remark. See Synonyms at joke.
- A moment; an instant: at the crack of dawn.
- Irish Fun had when socializing; social amusement.
- Slang Crack cocaine.
It seems to me that the sense 1b make some sense, which means that there isn't any slight narrow space in the unity. But I don't have the confidence. Can anyone help?
