without attacking their own people - not applicable
-Any country so- minded can attack us, there is no connection that I see between the potential for this and the flavors of people making up US.
- yes, US adopts a sufficient number of people that they rendered into refugee status but this is generally a small number sufficient for political purposes, photo-ops, campaign fodder and similar exploitation.
- when "we" began in ernest to destroy this country, the native continent and its people in the process of establishing America and the attendent we-the-people, "we" were largely white English with a smattering of imported black and or brown slaves. By the time of the Revolution "we" had grown in number of English and blacks & browns, in addition to French, Spanish and a broad smattering of other Europeans most who also brought their own black & brown slaves upon sailing enroute from UK and Europe to this side of the pond. This makeup "melting pot" did not seem to deter or impede English, French, Spanish et al coming from east of the pond to the western side of the pond to attack the the present make up of English, French, Spanish and etc "we". Since then the melting pot has attained many more various ethnic flavors & spices both willing and non but I do not see any connection of this being an obstacle to any country with desires to attack this country...... It just occured to me what a fitting / timely aspect there is to the front end of this US/invasion story.
